COMPARATIVE STUDY OF EARTHQUAKE-RESISTANT BUILDING DESIGN STANDARDS

Earthquakes are often disasters that cause significant damage to infrastructure, buildings, and even fatalities. As a result, many nations globally have established earthquake-resistant design standards to protect infrastructure, buildings, and human lives from the impacts of seismic events. The objective of this research is to evaluate the impact of implementing earthquake-resistant construction standards on the structural integrity and performance of buildings throughout Indonesia. The research was undertaken by comparing buildings designed based on SNI 1726:2019, Eurocode 8:2004, and IS 1893:2016. The method employed involves comparing both elastic and inelastic design results using pushover analysis for each standard to assess seismic performance using ETABS software as an analytical tool. Findings from the analysis reveal that structures designed following the SNI 1726:2019 required the smallest area of flexural reinforcement, followed by an increased requirement in Eurocode 8:2004, and the highest in IS 1893:2016. Furthermore, the nonlinear pushover analysis revealed that the performance point of SNI 1726:2019 was 8.38% higher than Eurocode 8:2004 and 24.03% higher than IS 1893:2016 in the X direction, and 12.15% higher than Eurocode 8:2004 and 27.76% higher than IS 1893:2016 in the Y direction.
