Building performance analysis through a combination of seismic ground response and structural dynamic analysis for educational buildings

This study integrates soil response analysis and structural dynamics analysis to evaluate the earthquake resistance of the Lecture Building of the Professional Programme at the Faculty of Teacher Education and Training (FTTE) and to determine wave amplification and propagation, as well as soil strength. The research process began with a site characterisation survey to collect geological data. Seismic soil response analysis was conducted to evaluate how earthquake vibrations propagate from deep soil layers to the building's foundations, and the results were subsequently used to simulate seismic loads on the building structure. Structural vulnerability was identified through an evaluation of the stress ratio. Several elements are highlighted in red, indicating that the building structure is overloaded or unsafe. In this study, the beams weakened. Components that did not meet the requirements were retrofitted to improve load-bearing capacity and structural ductility. The analysis results showed that these reinforcement methods significantly improved structural performance. The results demonstrated that the improvements significantly enhanced structural performance. This study highlights the importance of combining soil response analysis and structural dynamics to enhance the safety and resilience of buildings in earthquake-prone areas.
