Abstract
Cross transfer station plays an important role in the urban transit system, but few studies focus on its seismic performance. A 3-D numerical model of a typical cross transfer station structure-soil system is conducted based on the finite element code ABAQUS to study the seismic response under different ground motion directions. The Shanghai artificial seismic waves are chosen to be input. The structure and soil deformation are studied respectively. The structure deformation contains the relative displacement between the end well and intersection of the station structure, and the non-uniform story drifts of structural sections. The results shows the relative relation between the soil deformation and structure-soil stiffness.
