A 12 5 M Short Simply Supported Steel Beam And Composite Slab Bridge Shown Below Is Casted In One Stage The Bridge Co 1 (92.63 KiB) Viewed 45 times

A 12.5 m short simply supported steel beam and composite slab bridge (shown below) is casted in one stage. The bridge composite system utilises a 120mm thick cast in-situ reinforced concrete slab and casting takes place on profiled steel sheeting. The slab is to be supported by, and will act compositely with, parallel 610 UB 113 steel beams (Grade 300 steel). The beams, which may be regarded as simply-supported at both ends, will be spaced at 4.9m centre-to-centre and the concrete compressive strength is f = 40 MPa and y=0.77 for the composite slab. မူ & Bearings 12.5m Bearings Parapet Fal Steel beams RC wall River a) For the steel beams, check the shear capacity of the web and the web thickness of unstiffened webs (15 Marks); b) For the main mode of instability which is Lateral Torsional Buckling in the steel beams where the girders undergo simultaneous lateral movement and rotation, design appropriate steel beam bracing system (25 Marks); c) Determine the ultimate flexural strength of the proposed composite sections for the centre girders (40 Marks); d) Using 125PFC (parallel flange channel) with 150mm length channel shear connectors shown below, determine the appropriate spacing of the shear connectors to achieve full shear connection at the mid-span of the composite beams according to AS 5100.6-2017 (20 Marks).
