Abstract

Most regions of Indonesia are classified as earthquake-prone areas. The education is one of the sectors most affected by earthquakes. Records of major earthquakes show that not all educational buildings have adequate seismic performance. This study aims to assess the seismic performance of an existing multi-story educational building. If structural weaknesses are identified, mitigation measures can be formulated. In this study, the structural evaluation was conducted in two stages. Stage 1 evaluation used Rapid Visual Screening (RVS) based on FEMA P-154 guidelines. Stage 2 evaluation used equivalent static and dynamic response spectrum analyses based on ASCE/SEI 41-17 and SNI 1726:2019. The Stage 1 RVS evaluation produced a score of 2.1, which is below the threshold value of 2.5, so Stage 2 evaluation was required. Based on the Stage 2 evaluation, all column elements had Demand Capacity Ratio (DCR) values below 1 (linear elastic). Only some beam elements had DCR values between 1 and 2 (linear inelastic). The projected collapse mechanism satisfied the strong column–weak beam principle. No structural weaknesses that could trigger building collapse during an earthquake were identified. Stage 3 evaluation, namely nonlinear static pushover or nonlinear dynamic time history analysis, was not recommended.
