Influence of Dynamic Soil-Structure Interaction on the Failure Mechanism and Performance Level of Reinforced Concrete Buildings

Abstract

This paper deals with the influence of considering dynamic soil-structure interaction (DSSI) on the structural behavior of a ten-story reinforced concrete mixed typology building under seismic load. In order to do so, the non-linear static push-over method was implemented using the ETABS V17 software. The DSSI was included through the Pais & Kausel and Sargsian models, considering the characteristics of two types of soils: rigid and soft clay according to the NC 46:2017 [1]. As main results, when including the DSSI, an increase in the values of top displacement and drifts and a decrease in the values of basal shear for which the global fluency of the structure and its failure mechanism are reached, is observed. Additionally, the performance level of the structure is far from what is recommended by the codes.
