25 STRUCTURAL STEELWORK

25.1 GENERAL

In all bridge construction and bridge rehabilitation drawings prepared by the Authority, by Consultants for the Authority or for bridges that will become the property of the Authority, where structural steel elements are specified, the material used shall be in accordance with the relevant Australian Standard and this shall be stated on the drawings in the following manner:

" Steel plate shall conform to AS/NZS 3678-300 " " Steel sections shall conform to AS/NZS 3679.1-300 "

where 300 following the Australian Standard number indicates the grade of the steel in the plate or section.

Structural steelwork drawings shall show sufficient detail for the complete fabrication of a particular item or sufficient detail to enable the fabricator to prepare detailed shop drawings for the particular item. For simple fabrication work, such as bridge girders that are made from rolled steel sections, universal beams and built-up plate girders, shop drawings are not usually prepared.

Each item of fabricated steelwork shall be detailed in the form that the item is released from the fabrication shop with each and every part that is attached in the fabrication shop shown as part of the total assembly. Fabricated items that form part of the total assembly need not be detailed as separate items nor shall the quantity of those items be shown separately unless unduly complicated and in such a case, the quantity of those items be shown separately with the detail of the item.

In the majority of cases, it is sufficient to detail a fabricated item in one or two views, with enlarged details of the more complex portions as necessary

eg A normal plate with holes in it would require a plan view only. A tapered plate would require a plan and a section. A universal beam type girder would require an elevation and cross section. A fabricated item with a longitudinal axis of symmetry, such as a built-up plate girder, steel trough girder or steel box girder, would require an elevation and sections to depict different plate sizes and part plans to show all relevant details.

Where items are to be bolted or welded together in the field, eg where steel cross girders are to be attached to the main girders, an assembly drawing showing all components in their final position in the structure shall be provided. Where girders are bolted together in the field, the individual splice plates are supplied separately to the girders. Conventional practice is such that the holes in these plates are match drilled with the hole locations provided at the ends of each girder and in this case the detailing of each splice plate is not required as the assembly of the bolted splice is drawn in elevation, plan and cross section. The spacing of bolt holes and the edge distances to all plates shall be provided on these assembly drawings. Typical steelwork drawings, showing the method of detailing steel girders and their individual elements are shown in Figures 25.1(a), 25.1(b), 25.1(c) and 25.1(d).



25.2 STANDARD ITEMS

Standard items, such as bolts, nuts and screws need not be detailed fully. If items are not fully detailed, they shall be sufficiently described to enable correct identification eg M20 x 400 long high strength steel bolt, property class 8.8 to AS/NZS 1252, thread length 150, with nut, property class 8 to AS/NZS 1252 and 2 washers, normal series to AS 1237. Bolts shall not be described on drawings as M20 x 400 8.8/S and nut under any circumstances as the various Australian Standards for the bolts, nuts and the bolting category specified are not the same.

25.3 NON-STANDARD ITEMS

All non-standard items shall be fully detailed with all relevant dimensions, thread length, thread type and surface finish indicated as appropriate.

25.4 CLOSING DIMENSIONS

In accordance with industry practice, overall dimensions of steel items shall be provided to enable the correct manufacture of the items. Dimensions required for the correct positioning of holes etc in items shall be provided from one end only and as such no closing dimensions shall be given on the drawings.

25.5 WEB DIAGRAMS

Web diagrams shall be fully detailed to incorporate any camber requirements. Typical web diagrams are shown in Figure 25.5.1. Vertical dimensions may be related to a horizontal datum as shown in Figure 25.5.1 or alternatively, the web diagram may be detailed with the chord horizontal.

Where the appearance of the girder is of aesthetic importance, the top and bottom edges of the web plates shall be cut to form smooth curves to provide for the required camber.

25.6 STUD WELDED SHEAR CONNECTORS

The detailing of each and every shear connector in the plan and elevation of a girder is not necessary.

In elevations, shear connectors need only be shown where a change in pitch occurs.

In cross sections and enlarged details, all shear connectors shall be shown.

The size and length of shear connectors is a design consideration, however care shall be exercised to ensure that the shear connector detailed is appropriate and available.

25.7 WEB STIFFENERS

Where web stiffeners are provided and are not required to be welded to a flange, suitable clearance shall be provided between the web stiffener and the flange to allow for maintenance and painting requirements.

25.8 CORNER CUTS AND CUT-OUTS

When detailing the fabrication and assembly of steel members, radial corner cuts shall be provided to enhance weld clearance and the method of detailing corner cuts shall be as shown in Figure 25.1(d).



Where cut-outs are required in steel plates to provide clearance to existing members, the drawing shall clearly detail where the cut-outs are required and shall also include any relevant welding requirements as shown in Figure 25.1(d).

25.9 LIFTING LUGS

Steel girders and any other large fabricated steel item shall be detailed to include the provision of lifting lugs at suitable locations to facilitate the erection of the item.

Drawings shall also contain the following note as appropriate:

"All lifting lugs shall be cut off by a suitable method after final positioning of the girder and the remaining stub shall be ground flush with the top flange."

See Clause 25.10 of this Manual for the details of the renovation of galvanized surfaces where the item provided with lifting lugs has been hot-dip galvanized.

25.10 PROTECTIVE TREATMENT

The required protective treatment shall be specified on the drawings and it shall be appropriate for the item under consideration, ie for large items, it may be inappropriate to specify that the item be hot-dip galvanized after manufacture. In all cases where protective treatment of steelwork is required, the following note shall be included in the General Notes on the drawing: “Edges to be protective treated shall be rounded to a radius of 1.5mm unless noted otherwise”. Where fabricated steel items have been hot-dip galvanized and the surface of the protective coating has been disturbed or damaged for any reason, the following note shall be included in the General Notes on the drawing: “Damaged galvanized surfaces shall be renovated in accordance with RTA Specification B241”.

25.11 PLATE NOMENCLATURE

Steel plate sizes shall be shown on drawings using the width, thickness, length method eg 200 x 16 PLATE x 525 Where possible, standard plate widths shall be specified as this will reduce the need for plate stripping etc during fabrication of steel plate items.

25.12 INTERMITTENT WELDS Where structural steel sections or plates are joined together and the method of joining is by welding, welds shall be continuous for the full length of the interface in order to prevent long term crevice corrosion occurring. Intermittent welds shall not be used in structural applications.
