Some discussion on FE simulation of free field seismic response

XIE Zhentao1,WU Ti1,GAO Yongzhao1,ZHANG Junfa2(1.Sichuan Institute of Building Research,Chengdu 610081,China;2.Department of Civil Engineering,Xi'an University of Technology,Xi'an 710048,China)  
The practical project was regarded as the research background,according to advisement of choosing damp,partition of cell,boundary disposal and seism input,three different finite element model of layered soil was established based on ANSYS parametric design language.Through the seismic response analysis of this models,the result show that: although the three finite element model of layered soil in this paper have difference on simulative precision,they are all can significantly improve the simulation of free field seismic response.
