缓倾斜坡场地中多栋建筑地震响应研究
Seismic Response Study of Multiple Buildings in a Gently Inclined Slope Site
摘要
Abstract
To investigate the characteristics of the structure-soil-structure interaction in gently sloping ground,a series of two-dimensional finite element analysis models were es-tablished using ABAQUS software.The finite element models were subjected to static-dy-namic coupling analysis,taking into account the nonlinear characteristics of both soil and structure.Six different slope conditions ranging from 0° to 15° were set to explore the influ-ence of slope angle and spectral characteristics of the ground motion on the effect of the structure-soil-structure interaction(SSSI)in gently sloping ground.The results indicated that while the slope amplified the seismic response of structures located on the slope,it re-duced the seismic response of structures situated under the slope,and the degree of ampli-fication or reduction in some working conditions shown a certain pattern with the slope an-gle;the spectral characteristics of ground motion on the SSSI effect between structures was different and cannot be ignored.Low-frequency relatively abundant ground motion has a greater effect on the response of the peak acceleration and the interlayer displacement angle when the angle of the slope was changed.关键词
