Analysis and Design of RCC Girder Bridge

Abstract

Currently Construction industries doing research to find better safe and economic I-girders bridges. Girders have been found wide acceptance construction of highways and bridges due to their structural stability, economic in construction and long duration. In this paper comparative analysis of single span RCC Girder Bridge under IRC loadings and PSC Girder Bridge under IRS loadings. This Analysis has been performed using Ansys Workbench 15.0 software, 2D Drawing performed using AutoCAD 19 and 3D Modeling performed using Solidworks 16.0 software. For this analysis we have used three different types of girder cross section.First is Case A, in this case girder cross section have no cavity which means regular filled cross section. Second is Case B, in this case girder cross section have cylindrical cavity. Third is Case C, in this case girder cross section have cubic cavity. Each case have six load type conditions. First is Class A type of Vehicular Load as per IRC:6-2014, second is Double Headed Diesel Loco, third is Double Headed Electric Loco (2WAG9H), forth is Electric Loco [(B0-B0)+(B0-B0)], Fifth is With Double Head 25t LOCO and sixth is With Double Head 22.5t LOCO . In AutoCAD created 2D drawings and in Solidworks created 3D model using 2D drawing after that 3D model imported in Ansys Workbench 15.0 for applying load conditions according to bridges standard codes and then solved analysis. After solutions, it was observed that Case B is best model compared to another cases. Case B have less stress and less requirement volume of concrete mixture. So Design tools are very helpful to find out economic and better safe bridge parameters for constitutions.
