A railway bridge has nine 33.4 metre truss spans, six 19.2 metre through girder spans, seventeen 8.3m girder spans and the estimated width of the bridge is 5 metres Let's now assume that your truss is simply supported (one pinned support and one roller support) and that all members are pinned. 1. List all distributed forces that the truss needs to carry. 2. Find the total uniformly distributed force over 1m2 of the truss (kN/m2). 3. Considering the distance between the trusses, find the portion of the structure which is supported by each truss. 4. Convert the UDL to the nodal loads acting on the bottom chord's nodes of the truss. Each joint takes half of the UDL applied on the member to the left and half of the UDL applied on the member to the right.
