ABSTRACT

Soil-Structure Interaction (SSI) plays a significant role during seismic excitations for structures. Many researchers have assessed its importance for strategic structures such as bridges, hospitals, nuclear plants, neglecting its application to ordinary buildings. The present study aims at considering a 3D numerical simulation of a soil-structure system for these kind of structures, applying the open-source computational interface OpenSeesPL, implemented within the FE code OpenSees. This framework is capable of performing non-linear dynamic analyses and applying user-defined materials to model the soil. It is powerful in modeling the interface and boundary conditions that are of extreme importance in SSI problems. In particular, numerical simulations aims at performing the mutual behaviour of soil and structural deformability in order to assess safety and cost reduction. Therefore, this study can be considered one of the relatively few attempts to evaluate the necessity to consider Soil-Structure Interaction (SSI) in cases that actually are underestimated.
