    Abstract:

    There are more and more high-rise buildings erected on soft soil. The structure-soil-structure interaction cannot be ignored. Through finite element method, a series of three-dimensional models of structures and soil were built to study on the influence of direction of seismic motion, spectrum composition, shear wave velocity and damping ratio of subsoil, foundation form and depth, number of floors on SSSI effect. The calculated result shows that, SSSI effect can be ignored with seismic motion perpendicular to buildings' orientation; SSSI effect is directly bound up with spectrum composition of seismic wave; SSSI effect is apparent if shear wave velocity was slow, damping ratio was small, foundation depth was shallow, and the numbers of floors of buildings were the same.
