Performance of Integral Bridge by Addition of Cross Girders
Abstract: The bridges without expansion joints are Integral Abutment bridges (IAB’s). In conventional bridges, the bearings are generally corroded due to water seepage through joints which are avoided in IAB’s. However there will be stresses developed due to thermal induced movements of the bridge which is to be taken into account. In this paper, finite element analysis is carried out using STAAD ProV8i on a typical model of IAB. Here various …
