Review on Comparative Design and Analysis of RCC T-Beam Bridge Superstructure for Different Codes & Load Combinations

Abstract

This study reviewed comparative design and analysis of RCC T-Beam Bridge superstructure for Different Codes i.e., Indian Road Congress (IRC) codes and American Association of State Highway Transportation Officials (AASHTO) Specification & Load Combinations for varying span from 12M to 25M. The various codes are used to design the bridges. This is based on IRC 21-2000 for designing bridges by working stress method (WSM), also IRC: 112-2011 introduced by Indian Road Congress for RCC and Pre- Stressed bridges by limit state method (LSM). IRC: 6- 2017 is used for load considerations. Both the codes have different guidelines for design of bridges. In which this analysis depends on the analytical modeling by Finite Element Method (FEM) for in Staad-Pro software and comparing the structural parameter Bending moment, shear force, deflection and area of reinforcement for different girder span length as per the IRC and AASHTO code. Class A & Class 70R consider from IRC 6-2017 and HS20-44 is the vehicular loading consider from AASHTO. Form the analysis understanding suitability design technique and the behavior of T- Beam bridge superstructure under different loading condition and by using different code and comparing the result.
