<br/><br/> Earthquakes pose significant threats to human lives and infrastructure, prompting<br/>the construction of modern buildings to incorporate seismic resistance through<br/>performance-based design. Seismic isolation, a proven technology, minimizes structural<br/>damage by decoupling the superstructure from the substructure. This study analyzed the<br/>seismic response of the Delpan Evacuation Center under two scenarios: a fixed base design<br/>and a lead rubber bearing (LRB) seismic isolation system, using nonlinear time history<br/>analysis. The simulations were performed in ETABS v.21.1.0, adhering to ASCE 7-22 and<br/>ASCE 41-17 standards. Dynamic response parameters, including base and storey shear,<br/>storey displacement and drift, storey acceleration, and overturning moment, were<br/>compared. The LRB isolators were designed based on the maximum axial load carried by<br/>the columns. Among the trials, Trial 2 exhibited the best seismic resilience. The isolation<br/>plane showed increased displacements (184.125 mm to 204.428 mm) due to enhanced<br/>structural flexibility. Significant reductions were observed in interstorey drift (0.006 to<br/>0.012, within safe limits), base and storey shear (up to 57.24% in both X and Y directions),<br/>storey acceleration (16.43% to 50.54%), and overturning moment (26.26% to 60.64%).<br/>These findings demonstrate the efficacy of the designed seismic isolation system in<br/>improving the seismic performance of the evacuation center under earthquake conditions.<br/>The foundation plan and analysis were transmitted to the local government of Manila,<br/>providing valuable insights for the Department of Engineering and Public Works on the<br/>benefits of seismic isolation systems for critical infrastructure. This capstone project<br/>contributes to advancing seismic isolation technology and fostering further research and<br/>development in the Philippines.
