This study presents an integrated methodology combining ground response and structural dynamics analysis to analyse the earthquake-induced impacts on the resilience of the Integrated Laboratory building at the Faculty of Engineering, University of Bengkulu, during significant earthquakes. The investigation begins by conducting a site characterisation to collect geological data for the study location. A seismic ground response analysis is performed to assess ground motion at the pile tip, followed by the propagation of earthquake waves to evaluate the response of structures to earthquakes. Weak structures are identified through stress ratio evaluation, and retrofitting techniques are applied to enhance their load-bearing capacity. The results indicate that retrofitting has a significant improvement in structural performance. The study highlights the importance of combining ground response and structural dynamics analysis to enhance the safety and durability of buildings in earthquake-prone areas.
