建筑群结构-土-结构相互作用的影响参数研究
Parametric Study on Structure-Soil-Structure Interaction of High-rise Buildings
摘要
Abstract
With finite element method, a series of three-dimensional models of structures and soil were built to study the influence of seismic motion directions, the spectrum composition, shear wave velocities and damping ratios of the subsoil, the foundation forms and depths, floor numbers on structure-soil-structure interaction ( SSSI) effect.The calculation result shows that SSSI effect can be ignored when the seismic motion is perpendicular to buildings' orientation.SSSI effect is directly bound up with the spectrum composition of the seismic wave.SSSI effect is apparent if the shear wave velocity is slow, the damping ratio is small and the foundation depth is shallow, and especially the floor numbers of buildings are the same.关键词
