Abstract:The nonlinear earthquake response of two-layer double-column subway station built in Nanjing City is analyzed by ABAQUS software. The nonlinear characteristics of soil under cyclic loading is simulated by a dynamic nonlinear constitutive model proposed by authors which is implemented in ABAQUS software. The nonlinear characteristics of concrete under cyclic loading is simulated by plastic-damage constitutive model proposed by Jeeho Lee. The results indicate that dynamic stress concentrates in the junctions of side walls and level boards,and level boards and columns. Especially,dynamic stress concentrates severely in the junction of side wall and medial board,and columns and top or bottom boards. The junctions of subway station should be reinforced.
