Abstract
It is often necessary to cross a river or any other obstacle where no bridges exist or they have been collapsed due to natural disasters. In general already prefabricated bridge elements will be used. They are mostly made out of light as well transportable and detachable parts from high quality materials which could be fast to build Bridges with different span, width and load capacity. In the present paper behavior and performance of a Bridge, using three different types of truss members, namely Isotruss member, Box section and Circular tube, have been studied. Bridge is modelled and analysed using commercial Finite Element (FE) software. The Bridge is designed for a span of 10.50 m. Live load of 4 KN/m2 and wind load of 51.15 N, 70.34 N and 56.17 N applied as point load on Isotruss, Circular tube and Box section respectively are applied for designing the truss members. For serviceability condition stresses as well as deflections in members have been checked.
