Implementation of linear numerical analysis for integral abutment bridge-soil interaction

Integral bridges are bridges constructed with no expansion joints. Integral bridges are known for their superiority compared to conventional bridges which is well documented. The complicated soil-structure interaction presents a major uncertainty for integral bridges. This study describes the implementation of linear numerical analysis model which incorporates the soil response. Three models developed using Oasys GSA for the purpose of this study. The primary objectives of this study are to investigate the behaviour of structural elements of the integral abutment bridge under various load cases through finite element linear analyses and to identify a simple comprehensive model for numerical analyse of a typical integral abutment bridges. The findings of this study agree well with published work. Full meshed finite element model provides better understanding on separation between soil media and structure.
