Review of Design and Analysis of Box Girder Bridges And T-Beam Bridges Using IRC Codes

Abstract

Bridge is the structure which is used for carrying the traffic over the valley or river by connecting highways or railways. There are types of bridges which are T-beam bridges and box girder bridges where the T-beams are effective in resisting bending providing ductility to the bridges. While box girders gives high torsional stiffness providing ductility, stability and also aesthetics. Different codes with varying design philosophy are used for designing these bridges such as IRC:21-2000 and IRC:112-2011. Hence the purpose of this paper is to compare the results of analysis and design of different papers performed using these codes for both the types of bridges i.e. T-beam and box girder bridge. Various researchers studies are available on the design and analysis of T-beam bridge and box girder bridge using IRC:112-2011 and IRC:21-2000. The purpose of this study is to determine the most economical and preferable design code for both T-beam bridges and box girder bridges.
