Abstract: 3D finite element model is built in this paper, and seismic behavior of pile body of rigid pile composite foundation is studied by using response spectrum method and time history analysis method. According to similarity theory, pile group model of rigid pile composite foundation is established to analyze the response pattern with pseudo-dynamic test methods. And compared and analyzed the results which are obtained by different methods, whether bending moment or shear also are: the biggest is the corner pile, next is the side pile, and the smallest is the center pile; the displacement value difference is very little. The result shows that displacement distribution of rigid pile composite foundation is more uniform under seismic response; rigid pile composite foundation has excellent seismic behavior, based on observing experimental phenomena and studying theoretical and experimental data; pseudo-dynamic test method used to study the seismic behavior of rigid pile composite foundation is feasible; and it can be applied to the other test research of composite foundation with similar seismic behavior.

Key words: rigid pile composite foundation, response spectrum, time history analysis, pseudo-dynamic testing, seismic response
