Comparative analysis of soil-structure interaction (SSI) according to turkish and moroccan seismic standards

This thesis examines the soil-structure interaction (SSI) in structures built in accordance with seismic standards codes in both countries, Turkey (TBDY 2018) and Morocco (RPS 2000). The study focuses on understanding how variations in geotechnical and seismic standards impact SSI behaviors across both countries. With the purpose of analyzing the development of SSI considerations in both nations and determining the similarities and differences between TBDY2018 and RPS2000. This study conducts a comprehensive review of the literature to investigate the regional soil parameters and seismic factors that influence SSI in each nation. The findings are carried out by using finite element PLAXIS software to model SSI impacts, with a focus on how soil behavior differs between Turkey's complex, layered profiles and Morocco's generally uniform soils. The study's main focus is on analyzing soil classifications, seismic response modifications, and foundation interactions that differ according to local standards. The findings show that Turkish and Moroccan standards produce distinct settlement and load-transfer behaviors as a result of differences in soil qualities, seismic loads, and regulatory requirements. These findings highlight the necessity of customized and specialized foundation solutions that match regional circumstances in order to improve long-term structural integrity and reduce maintenance expenses for buildings.
