Research on Simulation Method of Steel-Concrete Composite Beam with Finite Element

Abstract

Abstract The performance of composite girder double element model and composite cross-section model in the finite element analysis of composite beam were introduced, and three simulation method of the interface in the composite beam was studied, and then the three finite element modeling method of were adopt to analysis a composite beam under different load, and two simulation models including shrinking and the creep effect were computed. It is concluded from the computational results, when the mesh of dual element model is refined, the difference between the calculation results of the dual element model and the transformed section model remains very small, which means that dual element model can meet the requirements of calculation accuracy in case of the fine mesh size.
