Kinematic SSI effects on seismic performance of RC structures
Abstract
In seismic regions, understanding soil–structure interaction (SSI) is crucial. This study examines the SSI effects on a six-storey RC-frame building using American guidelines for soil types B and C as per Eurocode 8. Structural responses of a constant structural system under various soil types and embedment conditions are compared, revealing significant influences on seismic behaviour. The study employs linear-elastic analysis to demonstrate that local soil and embedment conditions decrease base shear forces but increase total horizontal displacements and inter-storey drifts. This study highlights the importance of considering local soil conditions and embedment configurations to ensure structural resilience in earthquake-prone areas.
