Comparative study of box girder, suspension bridge & T Girder Bridge with varying spans

Abstract

In the present study three bridge models are considered box Girder Bridge, suspension bridge T girder bridge of lengths 100m, 120m and 140m consisting of two lane road network and the materials considered are M60 and Fe550 for concrete and steel and the structures modeled in CSIBRIDGE structural analysis and design software by considering various loads and load combinations such as dead load, live load, wind and seismic loads. And the results are compared between displacements due to dead and live loads, shear and bending moments in the sections and support reactions, suspension bridges shown better performance than box and T girder bridges.
