Abstract
Rod element and shell element were used in finite element software ABAQUS to establish dynamic elastic-plastic analysis model of the structure, the seismic performance of an irregular plane complex overrun structure numerical simulation, the structure was calculated under different input level and displacement response of the acceleration response, and analyses the force of the wear layer column and the floor of the open hole stress level. The results were compared with the shaking table test to verify the accuracy of the numerical simulation results. The results of numerical calculation were basically consistent with the experimental results, and the finite element model basically reflected the response of the structure under the simulated earthquake.
