Behaviour of Fully Integral Bridge over Indrayani River

Abstract

Abstract The Integral bridge have a continuous deck that is fully connected to the abutment. This study compares Fully integral bridge and Conventional simply supported bridge commonly under primary and secondary loads. Primary loads refer to the weight of the bridge, traffic loads, water current forces, wind load, seismic load and earth pressure calculations while secondary loads include temperature variations, shrinkage and other environmental factors. The research evaluates the effect of these loads on the structural behavior of the bridges and their resistance to deformation and failure. The bridge on Dehu-Sangurdi road near Pune is taken for case study. The length of bridge is 90 m with 4 spans of each 22.5 m. The STAAD Pro software is used to model and analyze the both type of bridges under different loading conditions. The research findings indicate that Fully integral bridge have higher resistance to deformation. The study compares the response of Fully integral Bridge and Conventional simply supported bridge to these loads based on deflection and bending moment parameters.
