Floor products to meet your specificationChoosing the correct floor deck product to suit your project specification can be challenging. With a comprehensive product range and wealth of technical experience, SMD has the profile to suit your needs.

Whether you are looking for a formwork-only solution or a product to form part of a structural composite slab, we have a range of floor deck profiles to suit all project and design drivers.

When choosing the type of floor deck profile to use there are many factors that need to be considered. These include span, composite beam design, slab design, loadings and construction methods. The most suitable product will depend on which of these criteria is your driving factor.

Whatever your design driver, a common goal is to reduce the need for temporary propping on site as this sterilises working areas and can impact on programme.

Our range of profiles from 50mm to 220mm deep are available in varying grades and thicknesses providing design flexibility to minimise propping in all scenarios.

This ‘White Book’ has been developed as a quick reference tool to be used by architects, engineers and specifiers when looking for a quick concept design for a composite slab. By following 3 simple steps, a suitable deck type/slab/reinforcement specification can be determined for your project.

The Three_step Process

Step 1, Which Profile and Gauge?Refer to Construction Stage graph on page 8.

Typically, spans are governed by the maximum 'unpropped' condition at Construction Stage. This graph considers the construction stage design and compares the different SMD profile/gauges based on decking sheets being double spans (unpropped).

By cross-referencing the slab depth / span, you can then determine which profile and slab depth best suits your proposed support configuration.

Note: Your product choice may also be governed by the stud requirements for your composite beam design.

Once you have reviewed this graph you should have confirmed profile type (TR50, R51+, TR60+, TR80+ or TR220), gauge and provisional slab depth.

All tables in this design guide are based on the standard S350 grade profiles. For S450 (or S250 for TR50) guidance download Elements® Design Software from www.smdltd.co.uk.

Step 2, Product specific composite slab graphsWith the profile confirmed from Step 1, refer to the relevant page for each profile, referencing the product graphs provides the Normal and Fire stage look-up check to ensure the slab depth proposed from step 1 meets your loading and fire rating requirement. The graph shows limits for loadings of 5 & 10kN/m² and fire ratings of 1.0, 1.5 & 2.0 hours.

By referring to this graph and checking the profile / slab depth from Step 1 you can determine suitability for the required loading and fire rating using either traditional mesh reinforcement or fibre reinforced concrete - in accordance with BS EN 1994-1-1.

Should the provisional slab depth from Step 1 not be appropriate for your required loading and fire rating, go back to Step 1 and increase the slab, profile and/or deck gauge.

After this step, you should have confirmed provisional profile, gauge and slab depth to suit the required design criteria.

Step 3, Confirm required reinforcement and maximum spans for your specific design criteriaHaving determined the slab depth required in Step 2, you can now determine the required reinforcement and maximum spans for your design (for both double and single span sheets, if required) using the product, fire rating and reinforcement or fibre concrete specific load/span tables. Each design table also enables you to assess the impact of increasing reinforcement, slab depth or profile gauge for UDL loadings of 3.5kN/m², 5kN/m², 7.5kN/m² and 10kN/m².

At the end of Step 3 you will now have a confirmed profile, gauge, slab depth and mesh reinforcement or fibre concrete for your slab. It should be noted that the design tables are based on minimum code requirements and the design assumptions on page 7.

In certain situations, increased reinforcement or slab depth will be required over and above that suggested within this guide, i.e. enhanced crack control, acoustic performance etc. This guide is provided as a design tool only and the ultimate design responsibility for the reinforcement / slab depth in the final condition remains that of the project structural engineer.

Product Span/Slab Depth Graphs

smdltd.co.uk 7 The White Book V4

Technical Design Table NotesThe load/span tables in this document are based on the following design assumptions.

17. Concrete volumes indicated in sectional properties are based on the slab poured to a constant thickness (recommended), additional concrete volume of span/250 m³/m² can be added to account for additional concrete as a result of deck deflection.

Reinforcement18a. All reference to traditional mesh reinforcement is based on

BS 4483.

Step 2 graphs for mesh reinforcement are based on a single layer of A393 mesh as for shallow slabs double layers of mesh may be difficult to install. It may be possible to reduce mesh at Step 3 depending on the governing design stage.

18b. All reference to fibre reinforced concrete is based on steel fibres in accordance with BS EN 14889-1 of type HE or HE++ (where indicated in the tables) with a fibre size of 1/50, available from ArcelorMittal Sheffield Ltd.

Step 2 graphs for fibre reinforced concrete are based on HE++ 1/50 fibre type at a dosage of 30kg/m³. It may be possible to reduce the fibre type and dosage at Step 3 depending on the governing design stage.

19. BS EN 1994-1-1 specifies 0.2% of the concrete above the ribs, where the mesh or fibre concrete equivalent does not meet this requirement no span value (-) is shown.

20 Top mesh cover of 22mm – Where this is not achievable due to the shallow concrete cover above the profile, no span value (**) is shown. It may be possible to achieve slab design in these situations by reducing top mesh cover or providing special mesh laps to enable nesting. For more information refer to www.smdltd.co.uk/tgn.

Fire21. Tables are provided for fire ratings of 1, 1.5 and 2 hours.

22. Where the slab depth does not provide adequate concrete cover to meet fire insulation requirement, no span value (-) is shown.

23. The Eurocode NCCI (mesh or fibre concrete only) method is used, therefore the composite slab and reinforcement (not necessarily the metal deck) must be continuous over one or more internal supports (end bay condition).

24. Load category A/B (Residential/Office) is considered where the imposed load is less than 7.5kN/m².

25. Load Category E is considered where the imposed load is 7.5kN/m² or greater.

26. All tables assume the fire insulation thickness required is achieved by utilising the structural slab thickness only. It may be possible to reduce structural slab thickness where a non-combustible screed is applied and additional bottom reinforcement provided. Elements® Design Software should be used to check such designs.

Spans1. Indicated in meters, from centre to centre of supports.

2. Based on 127mm support widths.

3. Double spans assume adjacent spans differ by no more than 15%.

4. In all cases, slabs are designed as simply-supported and in accordance with BS EN 1994-1-1 and UK NAD.

Note: In some instances the maximum single span may be greater than the maximum double span. This occurs where the composite or fire stage govern design, for single spans the concrete section is often increased due to ponding.

Loading5. FW in the design tables indicates maximum spans where

the deck is used as formwork only based on the mesh size indicated in the tables.

6. Applied loads shown in the look-up tables are un-factored, however, appropriate load factors have been taken into account in the derivation of maximum permissible spans.

7. Should include consideration for partitions, ceiling, services and finishes etc., but not self-weight of the slab as this has been included (where necessary) in the preparation of these tables.

8. Consideration should be given to any loadings that may be applied to the slab during construction (i.e. from plant or material storage), as these may be more onerous than the design loadings for the intended building use.

Construction Stage Loading9. Considers wet weight of concrete and reinforcement for the

specified slab depth.

10. Construction Imposed load of 1.5kN/m² or, 0.75kN/m² generally plus 10% slab weight or 0.75kN/m² (whichever is greater) over a 3m x 3m 'working area' in accordance with BS EN 1991-1-1.

11. Concrete volume/weight tables consider concrete only, they do not include the weight of deck or reinforcement.

Deflection12. Construction stage is limited to the lesser of Span/180 or

20mm when deflection is less than slab depth/10.

13. Limit increased to the lesser of Span/130 or 30mm, when concrete ponding is considered for deflections greater than slab depth/10. In certain design situations governed by fire, the span may be increased by considering ponding.

14. Tables do not include for any additional concrete as a result of deflection of the steel frame.

Concrete15. Typical concrete grade C25/30 with 20mm aggregate size.

16. Density in accordance with Eurocodes:

Normal Weight: 2550kg/m³ (Wet) and 2450kg/m³ (Dry)

All tables in this design guide are based on the standard S350 grade profiles. For S450 guidance download Elements® Design Software from www.smdltd.co.uk.

DescriptionUpdated from the original R51 product in 2018, this profile is available in S350 and S450 grades to provide the designer greater flexibility. R51+ is a traditional re-entrant profile commonly used on inner city multi-storey projects, where the structural zone and storey height is reduced, due to the relatively thin slab depth required to achieve a typical one hour fire rating.

Benefits • 102mm minimum slab depth

• Optimised to maximise structural efficiency of steel

• 150mm trough spacings provide flexibility for stud placement

DescriptionThe TR60 profile was SMD’s first trapezoidal profile, added to our product range in 1992. Further research and development in recent years has seen our trapezoidal products evolve into the TR+ range. The TR60+ profile enables un-propped spans in excess of 3.5m.

Benefits • Reduced concrete volume

• Enhanced speed of installation due to the 1m cover width

• Trough stiffeners positioned to ensure central stud position

Concrete Weight – These tables indicate concrete weight only and do not include the weight of decking or reinforcement. Concrete weights are based on the concrete densities specified in BS EN 1991-1-1 as follows: Normal Weight Concrete – 2550kg/m³ (wet) and 2450 kg/m³ (dry). Lightweight Concrete – 2050kg/m³ (wet) and 1950 kg/m³ (dry).

DescriptionInitially added to our product range in 2002, the original TR80 has undergone further research and development, evolving to the popular TR80+ profile in use today. This 80mm deep trapezoidal profile offers long un-propped spans reducing the number of structural support members required, making it a popular choice for low to medium storey buildings.

Benefits • Reduced concrete volume compared to other deck

available

• 140mm slab depth required to achieve a typical one hour fire rating

• TAB-Deck™ fibre concrete option

Concrete Weight – These tables indicate concrete weight only and do not include the weight of decking or re-inforcement. Concrete weights are based on the concrete densities specified in BS EN 1991-1-1 as follows: Normal Weight Concrete – 2550kg/m³ (wet) and 2450 kg/m³ (dry). Lightweight Concrete – 2050kg/m³ (wet) and 1950 kg/m³ (dry).

DescriptionThe additive floor TR220 combines high strength of the 220mm deep steel deck profile with the performance of a ribbed reinforced concrete slab to provide a long span floor solution. The use of TR220 installed to bottom flanges provides a slim floor construction to reduce the structural zone without the need for intermediate supports.

Benefits • Un-propped spans up to 6m

• Lightweight compared to other long-span flooring solutions

• Reduces structural floor zone, utilising slab depth within beam web supporting profile on bottom flange of beam

Concrete Volume and Weight

Deflection – This table is based on concrete poured to a constant thickness and does not take account for deflection of the decking or supporting beams (as a guide, to account for the deflection of the decking, a concrete volume of span/250 should be added to the figures indicated). Concrete Weight – These tables indicate concrete and reinforcement weight only, they do not include the weight of the deck. Concrete weights are based on the concrete densities specified in BS EN 1991-1-1 as follows: Normal Weight Concrete – 26kN/m³ (wet) and 25 kN/m³ (dry), Lightweight Concrete – 21kN/m³ (wet) and 20 kN/m³ (dry).
