Analysis of building structure performance due to earthquake load with time history analysis method using ETABS (Extended Three-Dimensional Analysis of Building Systems) software (case study: the faculty of medicine building at IGM University)

Abstract

The inability of a building to withstand deviations due to earthquake strength exceeding the required safe limit is one of the factors causing the collapse of the building. Mitigation efforts that can be made to overcome the impact of earthquakes include evaluating the performance of building structures. In this study, the Faculty of Medicine building at Indo Global Mandiri University was evaluated using the time history analysis method using ETABS V.18. The results of the analysis showed that for the El Centro (1940), Mentawai-West Sumatra (2007), and Chihuahua (2010) earthquakes, based on the value of inter-level drift and maximum inter-level drift on the effect of planned earthquake loads, the service limit performance was fewer than 0.017 meters and the ultimate limit performance was fewer than 0.080 meters, so it has met permit requirements according to the Indonesian standard (SNI 1726-2019) and is included in the safe category. Based on the performance of ATC-40 obtained for the El Centro (1940) and the Mentawai-West Sumatra (2007), it produced the performance level of the structure "Immediate Occupancy", while when subjected to the load of the Chihuahua (2010), it produced the performance level of the structure "Damage Control".
