地基土考虑材料阻尼影响的抗震性能分析
Seismic performance analysis of underlying soil considering material damping effect
摘要
Abstract
The seismic performance of an underlying soil model was conducted by finite element time-history dynamic analysis method by considering the material damping effect from different layers in the underlying soil and seismic reduction area. The soil model was numerically analyzed by a point pulse load atop its layer, the seismic reduction effect of the geometric size in seismic reduction area (including width, depth and its location) and material damping effect from the different soil materials were investigated. The results show that the less distance between the seismic reduction areas, the more effective in the seismic reduction effect. Greater width in seismic reduction area can be helpful to the seismic reduction effect. However, greater depth in seismic reduction area can be less helpful to the seismic reduction effect.关键词
