A Comparison Between Large-Size Shaking Table Test and Numerical Simulation Results of Subway Station Structure

Abstract eng:
Based on the large-size shaking table test results of subway station structure built in liquefiable site, considering the influence of soil-structure nonlinear dynamic interaction by 2D finite element methods, the seismic response of soil-subway station structure system under different test conditions are analyzed by using ABAQUS software. In the analysis model, dynamic visco-plastic memorial nested yield surface model is used to model dynamic characteristics of site soils, and plastic-damage model is used to model dynamic characteristics of concrete of subway station structure. And then, the numerical simulation results and the shaking table test records are compared in detail in this paper. The results show that the numerical simulation results of seismic response of soil-subway station structure system are basically identical with those of the shaking table test records. So that, the analysis results and the shaking table test results are proved to be correct.
