Introduction500PLUS REIDBAR is a continuously threaded steelreinforcing system manufactured and marketed in Australia byOneSteel Reinforcing and REID Construction Systems.

The 500PLUS REIDBAR technology was developed by REIDengineers after many years of research and was released in1995. A more efficient and simple way of joining reinforcingbar was needed by the industry. REID engineers observed thatthe normal deformation of rebar was like a thread, but couldnot be used for this purpose. They developed the concept ofdeformations forming a continuous right hand thread, whichcould then be adapted into a number of engineering solutionsfor connections in concrete construction.

Other mechanical splicing systems are commonly used butneed special joining equipment, training for operators and addto the complexity of the process on site. In addition, they aregenerally a much more expensive solution. The joining ofreinforcing bar using conventional lapping is the most utilisedmethod, mainly due to its relatively low cost. However, it is notas efficient and does not have the predictable performance ofmechanical systems. In a tension application, lapped bars areoffset to each other, which means that eccentricities need tobe considered. Furthermore, wastage on site is typicallyestimated as 10% or more.

500PLUS REIDBAR was the solution and overcame theseproblems. It provides an alternate solution to joiningreinforcing bar on-site. The simple method of applying a threadto the bar provides an effective method for joining, and hasled to a wide range of benefits in other types of connectionsrequired in concrete construction. A major benefit of the500PLUS REIDBAR system is that the cost is comparable withcurrent practice, and is more economical than any othermechanical system available.

The 500PLUS REIDBAR engineering principle is extremelyeffective when applied to starter bars for connecting slabsections, and replacing hooked bars in connecting pre-castpanels as it overcomes the lack of embedment depth foranchorage. 500PLUS REIDBAR provides a more effective

engineered connection in replacing the practice of bendingreinforcing bars into hooks and stirrups.

Another major benefit on-site is the lack of problems in theuse of 500PLUS REIDBAR, as it is simple to work with, and nospecial lengths are required. Connections are easy, the barcan be cut as required, the rugged threads are resistant todamage and the ability to join shorter lengths reduces wastage.

The introduction of 500PLUS REIDBAR has changed the wayengineers approach the design of reinforcing, and offerssignificant benefits in reducing labour and material costs. Italso facilitates improved engineering performance and reliableconnections in concrete construction. The product now haswide acceptance by the consulting industry and offers majorbenefits for rock anchoring, soil nailing and wind bracingapplications.

500PLUS REIDBAR has been developed through UniversityResearch Projects, extensive in house testing and by use inmajor engineering projects, both in Australia and New Zealand.OneSteel Reinforcing and REID have teams of engineersworking on new products and engineering solutions tocontinue the refinement of the product and the developmentof new ways that 500PLUS REIDBAR can benefit theconstruction and building industry.

Research work is fundamental to the OneSteel Reinforcingand REID approach to product development and for providingup to the minute solutions to the construction industry.

The 500PLUS REIDBAR system has generated innovativesolutions to the precast construction of multi storey buildings.REID’s current research program is at the University ofAuckland (Assessing the Seismic Performance ofReinforcement Coupler Systems by Anselmo Bai supervisedby Dr. Jason Ingham) and includes the design and testing ofprecast seismic beam column joints utilising the latestproduct ideas. OneSteel Reinforcing also has researchprograms at the Centre for Construction Technology &Research at the University of Western Sydney under thedirection of Professor Mark Patrick.

AS/NZS4671 defines the characteristic value as that value which has a 95% probability that it will not be lower than 95% of the minimum listed value, and not be higher than 105%above the upper listed value.Note: In the table above and subsequent tables Char Min = Characteristic Minimum, Char Max = Characteristic Maximum.* RB12 is MICROALLOY 500N other sections are TEMPCORE 500N

Youngs modulus (E) for both steel types is nominally 200GPa.

500PLUS REIDBAR satisfies the requirements of the standard for‘Steel Reinforcing Materials, AS/NZS4671:2001’. The bars arehot rolled with the deformations forming a continuous right handthread.

500PLUS REIDBAR supplied in Australia is a quenched and selftempered bar manufactured by the TEMPCORE process, exceptfor RB12 which is manufactured by the MICROALLOY process.Both manufacturing processes provide 500PLUS REIDBAR thatmeets the grade 500N designation.

The two types of bar require different welding techniques asshown in the welding section on page 38.

500PLUS REIDBAR is part of a system using a range of fittings tosimplify reinforcement detailing (nuts, threaded inserts, couplers,grout sleeves, anchorage plates etc).

All construction system fittings develop the breaking strengthof 500PLUS REIDBAR. (All nuts develop 1.15 x yield strength.)

Bar Slip

Common starter detail in a thin panel where embedment lengths may not meetcode requirements.

500PLUS REIDBAR inserts and footplates overcome theunder strength and slip deflection problems caused by usingbent bars, which have insufficient embedment.

Anchorage of 500PLUS REIDBARinto concrete is efficient and simple500PLUS REIDBAR is easily anchored using headedreinforcement principles (refer to the REID Studrail DesignGuide for details) by screwing on foot plates or threadedinserts. The anchoring foot is embedded with sufficient depthto develop the strength of the bar (see table 2 [page 13] andtypical details 2, 4, 5, 13, 19 & 20).

Hooked or bent Grade 500 rebars require an embedmentdepth of approximately 15 bar diameters if they are to meetconcrete design standards and are to be fully effective asflexural reinforcement.

This is often not possible in thin structural panels.

Note 1: The adoption of embedment depth L2 will ensure that the failure mechanism will be ductile rather than by brittle shear cone pullout.

Note 2: Embedment depth is calculated using the formulas developed by Haeussler. The general form is given as P = 0.972 x L2 x B2/3

where: P = pullout capacity of shear cone in NewtonsL = effective embedment depth in mmB = concrete compressive strength in MPa

(Test results have shown that pull out calculated with Haeussler will be about 15% conservative) (P.T. 2001)

Depth, edge and centre distanceeffectsThe design strength of concrete anchoring systems isdependent on many factors.

The five most critical are:

1. The compressive strength of the concrete.

2. The depth of embedment of the anchor foot.REIDBAR threaded inserts and footplates will develop thefull ultimate breaking strength of 500PLUS REIDBAR whenplaced at the embedment depth L2 shown in table 2. Atshallower depths the full breaking strength may not bereached and designers should apply the followingreduction factors to ascertain they have sufficient designstrength.

Reduction factors for reduced depths. To be applied to yieldand ultimate strength loads in table 2.

3. The shape of the anchor foot.REIDBAR threaded inserts and footplates provide a fullyeffective anchorage unlike a hooked bar with the sameembedment depth.

4. The proximity to other anchors.REIDBAR threaded inserts and footplates will develop thefull load capacity of the 500PLUS REIDBAR when placedat centres 6 times the minimum embedment L2 shown intable 2.

At closer spacing the full breaking strength of the bar may notbe reached.For example RB12 bars screwed into RB12TI (threadedinserts) at 300 centres in 25MPa concrete will still developthe characteristic yield strength (500MPa) of the bar but are

unlikely to develop the full breaking strength of the bar beforeconcrete rupture.(Bent bars at these centres and embedment depths can beexpected to provide significantly less capacity).Reduction factors for reduced bar centres to be applied toyield and ultimate strength loads in table 2.

This table applies to a single row of starters. If another row isrequired within 6L from this row, refer application toOneSteel. Correctly designed headed anchorages will alwaysoutperform hooked bars with the same effective depth.Reduction factors given will also apply to hooked bars.

5. Proximity to edges.REIDBAR threaded inserts and footplates will develop the fullload capacity of 500PLUS REIDBAR when placed at least 3times the minimum embedment (L2) from the edge of aconcrete component.Closer distances to edges will lead to the following reductionsin tensile capacity.Reduction factor for reduced edge distances.

500PLUS REIDBAR starter bar systems have been developedto provide full strength and positive connections betweenprecast concrete panels, floor slabs and insitu suspendedfloors. The system comprises 500PLUS REIDBAR ThreadedInserts, 500PLUS REIDBAR Starter Bars, specially designedPlacement Chairs, Nailing Plates and Antenna Caps.

The versatility of the system allows the contractor to set upthe Threaded Inserts prior to the panel being poured or to‘puddle them in’ before the panel is floated off. Whatever themethod used, 500PLUS REIDBAR starter bar systems offerstrength, stability, price effectiveness and ease of operationthat you just don’t get with standard NBar starter bars.

Features:• Available in RB12, RBA16 and RBA20 diameters – off theshelf.

• Thread diameter is true to size – not a N20 bar with athread turned down to 16mm.

• Coarse thread on the bar resists damage and minimizesforeign materials blocking the threads of the cast-inThreaded Insert.

• Coarse thread results in speed of application whenscrewing the Insert and Starter together.

• System components are purpose designed and offerspeed of set up and installation either in the Precast yardor on site.

• Non standard lengths are easily catered for as starterbars are cut from standard 6 or 12 metre lengths ofThreaded Reinforcing Bar.

Frequently Asked QuestionsQ How far into the coupler must the bar be

threaded?A Tests show that to achieve the ultimate strength of the

connection the thread engagement MUST BE AT LEAST80% of the maximum available in the fitting. Correct barinsertion is critical to the performance of the 500PLUSREIDBAR system. We recommend that good practiceREQUIRES the user to mark the bar at half couplerlength back from the inserted end so that a visual checkis available.

Q Is tightening torque critical in the performance of500PLUS REIDBAR components?

A Provided the bar is screwed tightly against the centrestop, or fully through the component, whichever isappropriate, the full breaking strength of the bar will bedeveloped. Does not apply to nuts as shown on page10. We recommend using a wrench with a minimumlength of 300mm to ensure the bar is fully engaged.

Q How much slip occurs in the thread of a coupleras it is loaded?

A Recent tests have shown that up to 0.5mm of slip canoccur in each end of the coupler at loads approachingyield. If this is an issue with crack widths at serviceabilitylimit state then couplers should be filled with REIDSwiftchem polyester resin at assembly. Tests with epoxyfilled RB16 couplers show slips around 0.2mm per endat 75% of bar yield. The effect of slip can be furtherreduced by staggering alternate couplers. An appropriatestagger distance would be the development length of thebar size being used. It should be noted however that inmost cases the 500PLUS REIDBAR fittings will be usedat construction joints which typically have crack widthswell above the coupler slip value.

Q How much slip occurs in the thread of a coupler ifnuts are fitted?

A Theory suggests that if we can induce a tension preloadinto a coupler which exceeds the required bar tensionthen no additional slip will be seen across the coupleruntil that pretension load is exceeded. Tests carried outat Auckland University in 2002 have shown that if thecorrect preload is applied using nuts tightened againstthe coupler ends, the coupled bar assembly will be stifferthan an unspliced bar at the same gauge length. Couplerslips measured across this gauge length are typicallyaround 0.1mm. Refer critical applications to REID.

Q What is the best way of cutting 500PLUSREIDBAR before joining?

A With an abrasive cutoff wheel or cutoff saw. Sheared orcropped ends usually present problems. Poorlymaintained equipment will leave a misshaped corediameter and excessive burr on the bar end making nutsand couplers hard to thread on. RB 12 can normally becut with a bolt cutter. Oxy acetylene cutting is a simpleand quick way of cutting large bars on site. Note:Starting the cut on the ridge of a 500PLUS REIDBARthread minimises heat input.

Q What end treatment is required before coupling?A If difficulty is encountered because of burring or

distortion of the end during cutting or shearing then alight dressing with an angle grinder to remove thedamage is all that is required.

Q What type of nuts should I use and when?A1 For most splicing and anchoring applications the primary

fittings (couplers, foot plates, inserts, grout sleeves)may be used without additional nuts. Tests havedemonstrated code compliance to meet the seismicrequirement of clause 7. 5. 1. 3 of NZS 3101:1995when the components are tested whilst embedded inconcrete. In order to satisfy the code, the spliced barmust not deflect more than 1.1 times the deflection foran equivalent gauge length of plain bar. StandardREIDBAR splices without nuts met the requirement. (Adiagram of the test rig is shown on page 9). Nuts arenot required with Grout Sleeves.

A2 Flange nuts (modified foot plates) and torque nuts.These are used for all designs where the nut is requiredto develop the full breaking strength of the bar e.g.terminations for rock bolts, ground anchors, hold-downbolts, tensioning applications etc. Torque nuts andflange nuts develop higher strengths to meet therequirements of NZ3101 for mechanical connectors.

A3 In critical applications (in plastic hinge zones) additionalnuts may be required to fully transfer load reversal underseismic events. In this case double nuts or torque nutsare used. Refer to questions/answers opposite on slipand pre load.

Q What testing has been done for 500PLUSREIDBAR?

A During the development of 500PLUS REIDBAR, extensivetests were conducted by REID to ensure compliance withall applicable codes, including the special seismicrequirements of New Zealand Reinforcement andStructural Design Standards. Tests have included cyclictension load tests, pullout tests to check embedmentanchorage, slip tests,etc. OneSteel Reinforcing and REIDcontinually monitor the system’s quality using accreditedtesting laboratories in an ongoing program of testing anddevelopment. Research continues to be undertaken.

Q Bending and rebendingA 500PLUS REIDBARs are highly ductile. 500PLUS

REIDBAR can be cold bent and rebent around theminimum former diameters specified inAS/NZS4671:2001 and NZS3402 without fracture.

The 500PLUS REIDBAR system can solve structuralconnection problems often encountered in thin sectionsor joints with thin panels. Refer detail 1a and 2 on page 8.

Q I want to bend large diameter bars. Can I heat500PLUS REIDBAR to assist in bending?

A1 RB12 is a micro alloyed bar and there will be minimalchange to the mechanical properties if the bar is allowedto cool in still air.

A2 RB16-32 are TEMPCORE bars and should not be heatedif the original mechanical properties are required.

Q Can I straighten an accidentally bent 500PLUSREIDBAR on site?

A1 RB12MA; YES, but with caution, especially if the bendradius is very small. Avoid using impact. It is better toheat the bar to a cherry red and rebend slowly. Allow tocool in still air.

A2 RB16-32TC; May be straightened cold provided due careis exercised and an appropriate method used tostraighten the bar. The bar should be closely examinedafter straightening to ensure that there are no visiblecracks in the bar at the rebend position.

Q Can I weld cast 500PLUS REIDBAR fittings?A Although Cast S.G. Iron fittings are weldable using

specialised techniques we do not recommend thepractice because the process will degrade the strengthand ductility of the fitting and therefore it will not meetits performance characteristics as stated in this manual.Hot forged nuts can be welded. Nuts manufactured fromfree machining steels can also be welded but cautionneeds to be exercised if load capacity is critical. ContactREID for further information regarding welding.

Q Can 500PLUS REIDBAR be hot dip galvanisedwithout loss of properties?

A1 RB12 is a micro alloyed bar with stable properties andmay be bent without the risk of cracking aftergalvanising. All bending/rebending should use thelargest possible bend radius. (Note: heavy coatings ofgalvanising on 500PLUS REIDBAR may preventcomponents being fitted. Refer all galvanisingapplications to REID local distributor.

A2 RB16-32TC will not generally be affected by hot dipgalvanising. However, it is not recommended that barsbent prior to galvanising be rebent. If this must beperformed careful checking for cracking should becarried out. All bending / rebending should use thelargest possible bend radius.Note: A galvanising thickness of 100 microns is allowedin the design of galvanised fittings.

Frequently Asked Questions

Q How do I connect one precast concrete elementto another using 500PLUS REIDBAR?

A Easily with the 500PLUS REIDBAR grout sleeve. A500PLUS REIDBAR grout sleeve is cast into the top ofthe lower element and a coupler into the bottom of theupper element. This eliminates the need for any starterbars protruding from the precast elements and which

are liable to damage and to be bent which makeserection difficult. Immediately prior to final placing astarter bar of the correct length is screwed into thecoupler and non-shrink grout is poured into the groutsleeve cup. The units are then brought together into thefinal position, levelled and propped.Note: this pre-grout method avoids the necessity forcasting-in grout tubes and the need for a separategrouting operation. (See typical detail 6A and 12).NOTE: TO EFFECTIVELY ANCHOR A GROUT SLEEVE ITREQUIRES AT LEAST A LAP LENGTH OF BARPROTRUDING SCREWED INTO THE THREADED END

Q What grout can I use in 500PLUS REIDBAR groutsleeves?

A Most general purpose grouts with a 28-day compressivestrength exceeding 65Mpa when used in a flowableconsistency. REID grout sleeves have been tested withFosroc Conbextra GP, Sika Grout 212, MBT 830.

Q What are the minimum cover requirements for500PLUS REIDBAR and components.

A1 Code requirements e.g. AS3600 requirements forreinforcement must be observed.

A2 Components. The two main factors to be considered areFire and Corrosion. Sufficient protection for thecomponents should be specified by the designeraccording to the fire, corrosion and other serviceabilityrequirements of the application, taking into considerationthe relevant codes and the following notes which providea guide for designers.

A3 Fire. The temperature of the steel reinforcing is affectedby the cover of concrete over the full extent of theembedded bar. The temperature is averaged over thesteel by conduction along its length which acts to quicklydissipate any localised temperature variations. A minorreduction in the cover in a very localised area (e.g. at acoupler) would therefore not lead to any significantincrease in steel temperature and no increasedreduction in strength.

A4 Corrosion.(1) 12mm (RB12 series) 500PLUS REIDBARcomponents and selected other fittings are made fromnormal steels and require the same cover as the baritself unless galvanised or otherwise protected.

(2) 500PLUS REIDBAR components in sizes larger thanRB12 are generally manufactured from specially alloyed,high strength, ductile iron. Ductile iron corrodes at about30% of the rate of reinforcing steels and the products ofthe corrosion are not expansive. As such ductile irondoes not lead to the spalling and flaking problemscommonly associated with the corrosion of steels inconcrete. Cover to Ductile Iron components can bereduced because of this good corrosion resistance. Wewould suggest that cover be maintained to at least 50%of code requirements for reinforcing steel. The exceptionto the better corrosion resistance of ductile iron is seawater and in that case it is preferable to use the samecover limitations as the bar

Frequently Asked QuestionsQ Does 500PLUS REIDBAR lose mechanical strength

when machined?A1 RB12, being a micro alloyed bar, will have homogeneous

mechanical strengths across the full cross section.

A2 RB16-32 are TEMPCORE bars and will not havehomogeneous mechanical strengths across the full crosssection.

Q How does 500PLUS REIDBAR starter bar comparewith a metric threaded starter bar?There are four issues here:

A1 The minimum core diameter of reinforcing bars do notallow the same diameter metric thread to be cut to a fullprofile.

A2 The thread cutting process will induce a notch effect atthe distal end of the thread and further reduce the barstrength, e.g., tests with M32 thread on a YD32 bar hadan ultimate capacity of 327kN compared with 504kNultimate for the unthreaded bar. RB32 bar maximumultimate 562kN.

A3 500PLUS REIDBAR threaded inserts have an effectivedepth allowing ductile failure at full bar strength. Metricthreaded inserts tend to be shorter.

A4 See TEMPCORE machining notes above.

Q Can I use the 500PLUS REIDBAR system attemperatures below freezing?

A All low temperature applications should be consideredcarefully, especially where impact loads are alsopresent. AS/NZS 4671:2001 has no impact testrequirement. Recent tests have shown values of Charpyimpact resistance for RB32 at -15°C at around 17joules. Grade 500/7 SG Iron is not recommended forservice at temperatures below freezing if impact loadsare present.

Q Can I use SG Iron REIDBAR components for lifting?

A No. In casting processes there is always a potential forcasting defects. While vigilant QA procedures are inplace, 100% inspection is not possible.

Q Is the performance of threaded inserts affectedby cracks?

A Yes. We recommend that the ultimate capacity ofthreaded inserts be reduced by 25% for crack widths of0.4mm and 30 - 40% for crack widths of 0.8mm.DO NOT PLACE THREADED INSERTS IN THE LIKELYBURSTING ZONE OF COVER CONCRETE TO TENSIONSTEEL.

Q What is the relationship between torque appliedto the nut and tension induced in the bar?

A The relationship of Torque versus tension in 500PLUSREIDBAR systems is reasonably linear up to about 25%of the bar yield strength. After this load, increasingtorque may not translate into increasing tension. Forreliable tension loads above 25% of bar yield the barmust be stressed by hydraulic or mechanical jacking.

Frequently Asked Questions

INCREASING TORQUE ABOVE THESE VALUES MAY NOT RELATE TO INCREASED TENSION

SOIL & ROCK ANCHORINGFeatures and benefits• 500PLUS REIDBAR has closely defined mechanicalproperties which provide consistent performance underlong term anchor loading.

• Unlike strand tendons the solid anchors have noconstructional losses.

• Supplied in the hot rolled condition which is effectivelystress-free.

• The high ductility and smooth, relatively flat rate of strainhardening ensures a high margin of safety againsttensile/shear overload in the case of transversemovements in the rock or soil.

• Resists dynamic loads (e.g. traffic wheel loads).

• Preloading to the full working load ensures that the loadtransmitted to the anchorage medium (rock or soil) isconstant i.e. live loads are not transmitted to theanchorage medium.

• A range of chemical and expansion anchors enhance theversatility of the system.

• Rugged thread is resistant to damage.

• May be tensioned, released and re-tensioned with ease

• Simplicity in applying the prestress with jacks, torquewrenches or air operated tools

• Recoverable anchors may be removed to simplify laterexcavations

• The rigidity of the anchors makes them easy to installespecially in overhead applications.

• High shear bond as deformations are designed for shearinterlock with concrete or resin.

• Transmits the anchor forces efficiently to the grout bodywithout additional fittings.

• Standard stock lengths may be stored and cut to suit theapplication.

• Offcut bars may be used for all standard concretereinforcement applications in the construction site whilstsmall pieces are ideal for formwork, starter bars orhangers in underground works.

• Can be cut and spliced at any point along its length

• Can be welded

Rock anchorsRock anchors have traditionally been grouted with cementgrouts. The ultimate strength of an anchor in soundcompetent rock is dependent on many factors. Among themore important of these is the unit bond stress capacity ofthe rock/grout interface, the unit bond stress capacity of thebar/grout interface, the length of the anchor and theconsequences of failure.

The capacity of the cement grout to both bond to and protectthe bar as well as to bond with the substrate is largelydependent on the water cement ratio.

“The bond and shear characteristics of a cement grout arealso determined largely by the water cement ratio. The idealwater cement ratio lies in the range 0.35 to 0.4 (Hyett et al.,1992). Cement grouts above 0.4 will cure with excessivemicro porosity and grouts below 0.35 could be difficult topump and may be susceptible to void forming and incompletewetting of the strata.”

As a practical guide a grout with a cement water ratio 0.35 isdescribed as ‘sticks readily to and hangs from the hand whenupturned’ and a ‘0.4 grout readily sticks to the hand but canbe shaken free’.

Rock/grout interfaceThe rock/grout interface is subject to so many vagaries thatthe choice of a suitable bond stress valueis often difficult.

As a general guide the ultimate bond stress for competentrock can be taken as 10% of uniaxial compressive stress(where the uniaxial compressive strength is above 20MPaand the bond stress is limited to a max of 4.2MPa) (afterLittlejohn and Bruce 1977).

Test bores will give a guide to the initial selection but on siteproof load tests are always advisable. The ability of rock toadequately confine the grout column reduces as the anchorlength decreases below 1 metre (after Morris and Sharp1973). We suggest that the bond strength of the first 600mmof the hole depth be ignored unless massive unfractured rockis at the surface.

NB: For working loads apply a factor of safety of at least 2.5 to these ultimate loads. The bond developed by added length of embedment may not be proportional to the additionallength. The load transfer mechanism between grout and fissured rock is much less certain and it is advisable to consolidate and seal the cracked rock by pregrouting beforeinstallation of the anchor.

Non-shrink groutsFor sites with limited or very restricted access, shrinkagecompensated, cement-based grout capsules are available.These capsules are supplied as a ready-to-use powderencapsulated in a water permeable skin. When required foruse the capsules are simply soaked in water for about 5mins which penetrates the skin and wets the powder, forminga plastic non-shrink grout. Capsules are 25mm diameter x320mm long.

Soil anchorsThe following tables (Tables 12 & 13) give guide values forthe load transfer capacity of various broadclassifications of non-cohesive and cohesive soils. A testanchor should be made to reliably determine the loadcapacity. The following information is provided for guidanceonly. A geotechnical engineer should be consulted todetermine the appropriate design requirements.

A more recent development for securing rock bolts, tie backsor rock dowels is to use resin to bond the 500PLUS REIDBARover part or all of the 500PLUS REIDBAR length. Very fastinstallation can be achieved using resin anchors.

Each bore hole must be cleaned out with air or water afterdrilling and before the resin cartridge is installed.Table 14 shows the correct cartridge to be used for each500PLUS REIDBAR size and bore hole diameter. Failure touse the correct diameters may result in inadequate mixing ofthe two part resin and reduced final bond strength.

Optimum performance of the 500PLUS REIDBAR anchor isachieved when the applied preload from final stressingexceeds the maximum applied working load of the anchor. Incertain applications pre-stress is not required and theanchors may be proof loaded to ensure integrity according tothe design requirement.

Stressing of 500PLUS REIDBAR is simple with either:1) a hollow bore hydraulic jack or2) a large torque wrench or air wrench. Refer Questions andAnswers, from page 21.

The anchorage length can be determined from the followingtable according to the calculated anchor load determinedfrom site conditions and design requirements.

Drill and clean holeDrill a hole with diameter in accordance with Table 14. Fordeep holes it may be necessary to drill a larger hole initiallyand reduce to the correct bore diameter in the deeper region.Remove all debris from drilled hole. Flush clean with oil-freecompressed air.

Insert Resin CartridgeInsert the required number of resin cartridges into the holeand carefully push them to the end. If an active anchorage isrequired, use the Duo-speed cartridge system which has afast setting resin at the leading end and slower setting resinat the tail end which sets after pre-stress has been applied.

Insert 500PLUS REIDBARSpin the 500PLUS REIDBAR anticlockwise for right handthreaded bar and clockwise for left hand threaded bar. Usean electric or air drill spinning at approximately 100 RPM.With the bar spinning, push the bar through the cartridgesuntil the bar reaches the base of the hole. Spin for a furtherten (10) seconds or shorter time if the torque on the drillbecomes excessive. Spin times are critical. Spin too short –incomplete mixing, spin too long – bar and resin interface willbe destroyed. Refer to instructions on resin cartridgepackaging.

Assemble End HardwareIf the 500PLUS REIDBAR is not perpendicular to the bearingface a special bearer plate and spherical washer is used.This arrangement will accommodate inclination up to 20°.See diagram below.

A bearer plate is not required when the Flange Nut bearsdirectly onto concrete with a compressive strength greaterthan 25MPa.

A bearer plate must be used when bearing onto low strengthconcrete, timber or natural soil or rock.

Apply Pre-stress LoadA pre-stress or clamping load can be applied to the anchoronce the resin has cured. Curing time varies according totemperature and type of resin but total pre-stress cannormally be applied after five (5) minutes. Pre-stress isapplied with a hydraulic jack, torque wrench or air wrench.Refer Questions and Answers, from page 21.

Tension/torque relationships for 500PLUS REIDBAR Anchorsare not consistent due to the wide range of variables.Where tensions must be preset use a calibrated jack.See Questions and Answers section, from page 21.

There are several methods available to anchor 500PLUSREIDBAR into concrete or other homogenous substrates.Starter bars are frequently located in critical stress zonesand consequently the following tables are based on the NZ3101:1995 requirement that bars in these zones develop thefull breaking strength of the bar at the interface of the newand old concrete. (This exceeds the less stringentrequirements of AS 3600 which suggests 1.1fy).

If starter bars are not in a critical stress zone, i.e. floortopping starters which will act mainly in shear, the holedepths and amount of resins can be reduced.

As a general rule, REID epoxy and polyester injection systemsas well as standard glass phials can be expected to developa approximately 14MPa adhesion between the resin plug anda good quality 30MPa concrete substrate. Hammer-in glasscapsules can be expected to provide approximately 12MPaadhesion.

Three common methods used to anchor 500PLUS REIDBARinto existing stone or concrete:

METHOD 1 -USING REID ‘HAMMER IN’ CAPSULES

DescriptionREID ‘Hammer In’ Capsules will anchor 500PLUS REIDBARinto rock, concrete or other homogeneous substrates.

Because of the unique design of the glass capsules the500PLUS REIDBAR can be simply hammered into the drilledhole in the substrate without any spinning of the bar.

The glass capsule contains a measure of resin and hardenerwith the hardener arranged in such a way that mixing willoccur without the need to spin the bar.

Directions for Use1. Holes of the correct diameter and depth should be drilledusing good quality drilling equipment, e.g. REID MultishankCarbide Drills.

2. Drilling debris and dust should be thoroughly cleaned fromthe hole using a suitable technique such as the stiff nylonbottle brushes available from REID. Compressed air orclean water is also commonly used.

3. Once the hole is prepared insert the correct capsule (orcapsules).

4. Hammer the end of the 500PLUS REIDBAR through theglass capsule until the bar reaches the bottom of thehole.

Caution: Always wear safety glasses when using hammer-incapsules

METHOD 2 -USING REID CHEMICAL INJECTION SYSTEMS

DescriptionREID offers a range of high strength epoxy and polyesterchemical injection systems which will anchor 500PLUSREIDBAR into rock, concrete or other homogeneoussubstrates.All of these systems utilise cartridges with self-mixing nozzlesthat automatically mix the resins and hardeners as theproduct is gunned into the drilled hole.

Directions for Use1. Holes of the correct diameter and depth should be drilledusing good quality drilling equipment, e.g. REID Multi-shank Carbide Drills.

2. Drilling debris and dust should be thoroughly cleaned fromthe hole using a suitable technique such as the stiff nylonbottle brushes available from REID. Compressed air orclean water is also commonly used.

3. Once the hole is prepared insert the nozzle of theinjection gun into the hole and inject the resin into thebase of the hole.

4. Push the 500PLUS REIDBAR through the mixed resin andhardener until the bar reaches the bottom of the hole.Rotate the bar four times by hand in an anti-clockwisedirection.

METHOD 3 -USING NON SHRINK GROUTS

DescriptionREID offers a non shrink, medium strength grout systemwhich will anchor 500PLUS REIDBAR into rock, concrete orother homogeneous substrates.

Directions for Use

1. Holes of the correct diameter and depth should be drilledusing good quality drilling equipment, e.g. REID Multi-shank Carbide Drills.

2. Drilling debris and dust should be thoroughly cleaned fromthe hole using a suitable technique such as the stiff nylonbottle brushes available from REID. Compressed air (oil-free) or clean water is also commonly used.

3. Once the hole is prepared fill with grout to 3/4 depth.

4. Push the 500PLUS REIDBAR through the grout until thebar reaches the bottom of the hole. Slowly rotate the barfour times. Remove excess grout or top up as necessary.

5. If core drills are used the hole should be chemicallyetched to roughen the bore.

Bracing & Tie DownFeatures and benefitsBracing:• Simple bracing system for all applications where rodbracing can be used.

• Very cost effective – saves time and money overtraditional methods.

• Uses standard end fittings and 500PLUS REIDBAR.

• No more welding of special fittings for bracing assemblies.

• No more threading of bar or rod.

• No more fabrication of bracing components.

• Versatile – a range of standard end connections used withstandard 500PLUS REIDBAR fits most applications andsituations.

• May be galvanized and used with galvanized 500PLUSREIDBAR for added durability.

Tie down:• 500PLUS REIDBAR provides cost effective solution totransfer tension/uplift forces to secure supports e.g. roofto foundation connection.

• Suits most construction methods and materials.

• The REID range of chemical anchors and 500PLUSREIDBAR fittings allow a variety of solutions for anchoring500PLUS REIDBAR to concrete foundations/ supports.

• Standard 500PLUS REIDBAR, nuts and associatedcomponents of the 500PLUS REIDBAR system are readilyavailable and do not require additional preparation.

500PLUS REIDBARS are ideal for tie-down bars for lightweightmasonry, brick, steel framed, timber framed or solid timberstructures.

In extreme wind conditions such as Northern Australia 12mm500PLUS REIDBAR (RB12) greatly simplifies compliance withbuilding code requirements for cyclone tie-downs for all typesof building construction.

Using designers can simply and economically provide acontinuous tie from the building footing to roof truss that caneven be post tensioned to improve the structuralperformance of the wall unit.

Post tensioning wall ties can provide many advantages.

• Reduces flexural tensile stress in masonry walls.

• Improves stiffness of wall diaphrams.

• Reduces the likelihood of leakage due to shrinkage cracksin concrete or masonry.

• Reduces deflections in structural elements.

• Reduces thermal movement in solid timber constructionsystems.

WELDINGFeatures and benefits• 500PLUS REIDBAR systems are designed to eliminate orreduce the need to weld reinforcing bars. Site conditionscan often make it difficult to control both weldingprocedures and proper consumable selection.

References, standardsAS1554 Part 3 1983 and the WTIA technical note 1.

Joint designRefer to AS1554 Part 3

Choice of welding processThis grade of steel is readily weldable by either metal manualarc (MMA) or semi-automatic and automatic (SUBARC) orinert gas shielded (MIG) processes.

Optimum results are obtained with MIG and automaticprocesses.

ConsumablesWhen using MMA welding processes, we recommend the useof Hydrogen Controlled electrodes.

Note: 500PLUS REIDBAR 12mm origin is micro alloyed bar and can be welded using the procedures outlined. 500PLUSREIDBAR 16-32mm is manufactured by the TEMPCORE process and can be welded using the procedures outlined.


38


Concrete reinforcing and weldingCareful design, process specification, qualification andcontrol is vital for the integrity of weldments.Welding processes can produce undesirable metallurgicaldefects in the steels being welded and in other adjacentmaterials subject to arc strikes and weld spatter. Defectsintroduced during welding can embrittle steel and providedsites which act as stress concentrators, causing unexpectedmodes of failure. For this reason some codes prohibit, orrestrict the welding of reinforcing bars used in concreteconstruction.

As a general rule we do not recommend welding ofreinforcing bars – especially on site where the required levelof quality and supervision can be difficult to maintain. Wherewelding is required it should be critically supervised andcarried out under carefully controlled conditions by suitablyqualified welders and welding processes. Where bars are tobe positioned in pre-fabricated cages, consideration shouldbe given to tying rather than welding bars. Mechanicalconnection of bars using the benefits of 500PLUS REIDBARprovide effective alternatives for joining bars both in thefactory and on site.

Effect of heating on mechanical propertiesThere are two methods for achieving the required mechanicalstrengths of reinforcing bars:

• Addition of alloying elements to the steel

• Thermally treating the bar (cold water quenching andtempering)

Bars which are cold worked or thermally treated to increasetheir strength, loose mechanical strength after heating. Thesebars cannot be heated before bending and can be adverselyaffected by welding processes. Great care and control mustbe exercised when applying heat to such bars to ensure thatthey do not exceed the critical heating temperature at anypoint. This is recognised by AS3600 Clause 19.2.3.1 whichlimits the design strength to 250MPa for bars heated inexcess of 450°C.

RB12 500PLUS REIDBAR is microalloyed and retains its fullstrength and ductility on cooling after being heated totemperatures in excess of 600°C.

RB12 500PLUS REIDBAR may be heated to assist bendingwithout risk of reducing the mechanical properties, unlikecold worked or thermally treated bars.

See Questions and Answers section, pages 21-22.

RB12 MICROALLOYWelding arc energy (heat input)We recommend that a minimum welding arc energy of2kJ/mm be used for all processes.

The use of well controlled, high heat input processes isespecially important for tack welds, to reduce the risk forundesirable hardening in the heat affected zones adjacent tothe welds.

Choose the largest diameter electrode possible for the job.

The electrode chosen should never be less than 3.2mmAs a guide the following minimum electrode sizes should beused for all welds including tack welds:

Electrode diameters.

Tack WeldsTack welds should be made with high heat inputs. In practice,this may be achieved by selecting the largest possible size ofelectrode to ensure adequate heat input.

AS 1554 provides appropriate requirements for tack welds.We recommend that tack welds on large diameter bars bemade by MIG processes. In practice it is doubtful that tackwelds on bars larger than 25 mm would be made with MMA.

PreheatingHeating of steels prior to welding reduces the risk of crackingin the heat affected zones.

Regardless of the grade of steel, the best welds are achievedwhen the steel temperature prior to welding is at least 20-25°C.

Welds should never be attempted at temperatures below 0°Cwithout preheating. In cold weather where such temperaturesare expected it is essential to preheat the steel to 20-25°C.Whilst good quality welds can be achieved in many steels atambient temperatures above 0°C, the weldability andresistance to cracking depends on the steel chemistry and anumber of factors which influence the rate of cooling from thewelding temperature. These include the initial temperature of

the steel, the physical size and mass of the pieces beingjoined, the size and shape of the weld, the welding heat inputand the ambient temperature.

No additional preheat is required for any size of 500PLUSREIDBAR when the welding arc energy exceeds 2kJ/mm.

Bars of 32mm diameter and larger require higher levels ofpreheat only when welded with arc energies less than2kJ/mm. In practice it is unlikely that such low arc energieswould be used for welding bars of this size.

500N 500PLUS REIDBAR produced by the TEMPCOREprocess has a carbon equivalent (CE) limit of 0.44 max and,as such, requires no pre-heating prior to welding.

Users should also be aware that hydrogen controlledelectrodes will be required for all weld types, andmatching strength electrodes will be required for butt welds.

GENERAL RULES FOR THE WELDING OF 500N500PLUS REIDBARAll welding must conform to the requirements of AS/NZS1554 part 3, 2002.

PreheatNot required

Post HeatNot required

Electrode Type• Hydrogen controlled welding processes and electrodessuch as GMAW (MIG), FCAW and low hydrogen MMAW(sticks) must be used for all weld types. Correct control,storage and drying of electrodes is essential.

• Matching strength W55x (E55xx) or W62x (E62xx) typeconsumables are required for all load bearing butt welds.

• Under-matching W50x (E48xx) and W41 (E40xx)electrodes may also be used for lap and other weld typeswith appropriate weld lengths as shown in the followingsections.

• Select electrode diameter to be compatible with size ofbars being joined.

Interpass TemperatureThis should be limited to 200°C maximum for all joints.

Welding Technique & heat InputBest results are achieved using stringer beads where heatinput will generally not exceed 2.5kj/mm. Weaving is notrecommended.

Welding Practice Notes• Observe 200°C maximum limit on interpass temperaturesfor TEMPCORE.

• For multiple welds, interpass temperature rise can beminimised by laying weld beads on separate joints insequence thus allowing each weld to cool between runs.As interpass temperatures are likely to increasethroughout, check the interpass temperature prior tocommencing each weld run.

• Balance welding on each side of joint as required tominimise distortion.

• For butt welds, back grind root run prior to completing thejoint.

• Clean and dress each weld run prior to deposition ofsubsequent runs.

• Refer to electrode manufacturer’s recommended currentranges and shielding gasses.

General NotesNon-symmetric joints such as lap welds may not be suitablefor use in seismic applications – specialist advice should besought in such cases.

General NotesThese are usually used forpositioning and holding purposes,and in prefabricated elements.

They must not be used for liftingpurposes unless prior approval hasbeen obtained from the designengineer (see AS/NNS 1554.3).They do not affect the strength of500PLUS.

Double Sided TackWeldsElectrode TypeMatching and under-matchingstrength electrodes may be used.

Weld LengthMinimum total weld length is 5d

General NotesThe short length of conventionaldouble sided lap splice welds maycause excessive rotation at thesplice when loaded in tension, andthus contribute to concrete spalling.Longer weld lengths than thatrequired to develop full strength havetherefore been recommended. Thistendency to rotate can be furtherminimised by forming the weld in twoparts as shown, thus increasing theeffective geometric length. In thiscase, the gap between lap weldsshould not exceed the total weldlength.

Single Sided LapWeldsElectrode TypeMatching and under-matchingstrength electrodes may be used.

Weld length• Matching strength electrodes: 8d• Under-matching W50x (E48xx) typeelectrodes: 9d

• Under-matching W41x (E41xx) typeelectrodes: 10d

General NotesSingle sided lap welds, because oftheir greater length, have lesstendency to rotate, but should onlybe used with the permission of thesupervising engineer when access tothe second side is not available orimpractical. These welds may alsobe formed in two parts as shownprovided total weld lengths noted areused.

Strap WeldsElectrode TypeMatching and under-matchingstrength electrodes may be used.

Weld LengthsWelded one side: 5d for eachindividual weldWelded both sides: 3d for eachindividual weld

General NotesFull parent bar properties aregenerated by strap welds. The totalsectional area of the splice barsmust not be less than the crosssectional area of the parent bar.

The gap between parent bars mustnot exceed 20mm.

Strap welds may be welded either onone side or both sides notingminimum effective weld lengthsabove. Strap welds are bulkier thanlap or butt splice joints thus may notbe suitable for use in applicationswhere concrete cover is minimal.Where doubt exists, verify suitabilitywith the supervising engineer.

Butt WeldsElectrode TypeMatching strength electrodes areessential to develop full strength inthe butt weld.

General NotesObserve 200°C maximum interpasstemperature by allowing weld to coolbetween runs, particularly towardsend of welding for TEMPCORE.
