Numerical Simulation Analysis of Seismic of Frame Structure on Hill Terrain

In recent year, Wenchuan, Ya'an, Yushu and other areas in china occur a series of high earthquake, however areas of earthquake is similar as mountainous terrain, building structure of seismic increasingly aroused our concern, and the research that hill topography affected building structure seismic in shallow mountain. The research content mainly includes: through modelling was built by the ANSYS software, the cooperative effects of a ten layer of frame structure- hill system were calculation. First, simple comparative dynamic characteristics analysis of soil - structure interaction and the rigid foundation assumption conditions; Second, put Hill-Soil-Structure Interaction(referred to as HSSI) and Soil - Structure - Interaction(referred to as SSI) further analysis of the dynamic response, including: including structural modal analysis (vibration mode, cycle), the time history analysis (such as displacement, internal force and acceleration) and so on. Through Hill-Soil-Structure Interaction research, taking each factor in consideration, giving structure seismic key technology measures about shallow mountain to provide reference for such structure theory research.
