Abstract: The dynamic Davidenkov model is used to model dynamic characteristics of soils,and plastic-damage model is used to model dynamic characteristics of station structure concrete.So that,considering the influence of soil-station structure interaction for 2D finite element analysis,the dynamic interaction of soil-station structure is modeled.The damage characteristics and energy response of station structure under seismic motion is analyzed.The result shows that damping energy and hysteretic energy are monotone increasing under ground motion,and the seismic characteristic has significant effect on the energy response of subway station structure.Furthermore,concentration effect of hysteretic energy of subway station structure is measured by hysteretic energy density.It is found that the hysteretic energy is the most centralized in the column,so the dynamic response of the columns is the maximum.Furthermore,the nonlinear damage evolution law of station structure is analyzed.The law of local and global damage index is consistent essentially,and the damage index is increased by the effect of accumulative deformation.
