Design for Economical Bridge Member for Steel Truss Which Replaced By Steel Girder for Foot Over Bridge

Abstract

Bridge, which is a structure that is constructed for crossing purposes. This analysis and design for Foot Over Bridge for 20 meter medium span length by using the Staad Pro software considering wind and seismic load in Mumbai region. This analysis is focusing on girder bridges being replaced by trusses, making bridges economical and safe with less steel consumption. The yield strength utilized by the girder is 430 MPa and for the truss is 240 MPa. The analysis found  the strength utilized by girder is almost 1.8 times more for making bridge element safe design than truss with same loading conditions. The result shows that the girder requires more material consumption than truss, as well as that cost required for girder is more than truss. The truss is good option for replaced with a girder. The benefits of this analysis is that to know the following reasons, the project is which economical and which bridge type consumes less material.
