steelwise - AISC Homecontrolling plate strength, we find the following weld leg size required: Min (0.3 F u t, 0.4 F y t) = 29.7 w Therefore, the required weld leg size is the lesser of 0.3 F u t /29.7 and 0.4 F y t /29.7. For ASTM A36 plate, the size of the two-sided fillet weld must be 0.49 times the thickness of the plate to match the strength of the plate.INDIAN RAILWAY STANDARD CODE OF PRACTICE FOR WELDING IN STRUCTURAL STEEL BRIDGES CARRYING RAIL, RAIL-CUM-ROAD OR PEDESTRIAN TRAFFIC (Welded Bridge Code) 1.

FIELD WELDING PROCEDURES - NCDOT1072-20 makes reference to the ANSI/AWS/AASHTO Bridge Welding Code D-1.5 and states in section 1072-20 (B) General Weld all structural steel in the shop or in the field for bridges, whether permanent or temporary, and perform all other work related to structural weldingDesign of steel footbridges - SteelConstruction.infoA typical bridge over a river or canal might then have a span of 30 m and a beam depth of 1 m. A simple I-beam bridge with non-structural floor might comprise two girders about 1.5 m apart on which is fixed a floor of, in some instances, timber planks. Parapet posts would be fixed to the top flange or the outer face of the steel beams.
WELD DESIGN CONSIDERATIONS FOR BRIDGE GIRDERS Bridge girders are usually fabricated using automatic welding techniques such as SAW and FCAW. Welding fabrication costs of the girders are heavily dependant on joint/weld design specified by the designer. Ideally, everything required to design a bridge would be covered by published standards.LRFD Steel Girder SuperStructure Design Example - LRFD , for welded structure sa36 bridge width

The size of the seal weld may not be specified, resulting in a weld that would otherwise be disallowed by Table 5.8. It is still important that good weld-ing practices be followed when seal welds are made, including adherence to the minimum fillet weld size. Failure to do so may result in weld cracking or incomplete , for welded structure sa36 bridge widthSPECIFICATIONSUp to a thickness of 14 mm it may be shop or field welded by normal procedures, but in greater thicknesses, because of the higher phosphorus content, there may be a tendency towards brittleness in the heat affected zone of welds. This type of steel is therefore normally limited to a thickness of 14 mm.

The availability of plate material varies from mill to mill. Generally, plates are available in minimum widths ranging from 48 to 60 and in maximum widths ranging from 150 to 190.Fatigue Analysis of Welded Structures Using the Finite , for welded structure sa36 bridge widthstructure components.
