Abstract

Earthquakes have the potential to cause significant damage to multi-story buildings; therefore, structural systems that can improve seismic performance are required. This study aims to compare the structural response of a 10-story office building in Surabaya using fixed base, shear wall, and base isolation systems with High Damping Rubber Bearing (HDRB). The analysis was conducted using ETABS software in accordance with SNI 1726:2019, considering parameters such as inter-story drift, base shear, structural period, and P-Delta effects. The results indicate that the shear wall system provides the highest stiffness, while the HDRB system significantly increases the structural period and reduces inter-story drift in the upper structure. Although it results in larger deformation at the base, the HDRB system still meets the performance criteria and is recommended for buildings in seismic-prone areas.

Abstract

Indonesia is a region with high seismic activity, including Surabaya, which is influenced by the Kendeng Fault. This study aims to analyze the effect of using High Damping Rubber Bearing (HDRB) on the seismic performance of a six-story office building. The analysis was carried out using ETABS based on SNI 1726:2019 by comparing a fixed-base structure and an HDRB-isolated structure. The parameters evaluated include natural period, base shear, interstory drift, and P-Delta effects. The results show that HDRB increases the natural period and significantly reduces base shear and interstory drift. Therefore, HDRB is effective in improving seismic performance and can be considered as an alternative design for buildings in moderate seismic hazard areas.
