INFLUENCE OF 2D AND 3D SOIL MODELING ON DYNAMIC NONLINEAR SSI RESPONSE

摘要：

The purpose of this paper is to investigate the accuracy of 2D FE plane-strain computations compared to complete 3D FE computations for dynamic non-linear SSI problems. In particular, this study is focused on the effect of non-linear soil behavior on the dynamic response of the reinforced concrete multistory frames.An balanced 2D plane-strain approach is presented and several numerical FE simulations using this approach are carried out using a plastic-hinge column-beam model to represent the concrete elements behavior and a realistic elastoplastic constitutive law to represent that of the soils.
