Abstract. Indonesia is one of the countries with a relatively high frequency of earthquakes, which can impact buildings and infrastructure. With the ongoing updates to regulatory codes, there will be an elevation in the level of safety factors in building design. Concurrently, there will be an increased prevalence of incorporating seismic hazards into the design of new buildings. Apart from that, earthquake loads can cause the performance of flat-plate structures to decrease until they collapse. Therefore, in this research, a case study of the existing office building with a flat plate structural system built in 1998 will undergo a seismic evaluation based on ASCE 41-17 to determine whether the building’s performance is still safe. The office building was evaluated at the Collapse Prevention performance level for the BSE-2E seismic hazard (975-year period) according to ASCE 41-17. The evaluation occurred in three stages: tier 1, tier 2, and tier 3. The pushover analysis demonstrates the use of linear and nonlinear static procedures in structural analysis. The evaluation indicated that the current office building could meet the specified performance level; however, several beam and column structural components still required fixing.
