Research Abstract

In order to establish a high qualified seismic 3-dimensional nonlinear response prediction method of soil foundation super structural systems in near seismic source, (1) a numerical method of the stress strain level's (micro model) nonlinear seismic response analysis of the foundation structure system is developed. Also, in this study, (2) a theoretical method of simulating deterministically the spatial variability of near field ground motions is proposed. The near field ground motions with large permanent movements due to a fault are simulated using the stiffness matrix method and kinematical model of fault rupture in horizontally homogeneous layered half space.
It is found from this study that the spatial variability of ground motions strongly affect on the inelastic response behavior of the lifelines near a fault and also that the nonlinear soil foundation seismic interaction affects upon the nonlinear response behavior of super structures such as cable stayed bridge and large scale BGF gas holder.
