Numerical Simulation of Shaking Table Test of Tianjin Transportation Junction

Abstract:

A shaking table test of large-scale pile-soil-complex structure interaction is accomplished on the transport hub of Tianjin station, and some reliable testing data of soil-structure dynamic interaction laws are acquired. ANSYS is used to simulate the process of the test, including establishment of 3D FEM model, selections of material parameters and constitutive, treatment of boundary conditions. Comparative analysis is performed between simulation data and testing data. The results show that: the simulative results agree well with the experimental ones under small earthquake, but the deviation increases when it suffers medium earthquake. The rationality of the numerical simulation and test are verified by each other, and the causes of the deviation under medium earthquake are analyzed.
