Dynamic structure-soil-structure interaction of piled high-rise buildings under earthquake excitations II: Influence of key parameter

Abstract A numerical study is performed on the structure-soil-structure interaction (SSSI) between high-rise buildings. ANSYS has been further developed for calculation in frequency domain, which hysteretic damping can be considered both soil and structures. This presented two subsequent papers. The first part[1] focuses influence of SSSI each kind dynamic response, while second part, i.e., this paper, a parameter that key parameter, including separation distance structures; ratio, thickness shear wave velocity soil; length pile; style, material stiffness, mass story number superstructure; position structure, SSSI. decreases with increase structures, ratio soil, superstructure, or decrease stiffness superstructure fluctuating manner.
