520			_aThe Philippines faces increasing concerns over frequent seismic events, including the potential occurrence of "The Big One," a large-scale earthquake associated with the Marikina Valley Fault. This study evaluates the effectiveness of base isolation systems in mitigating seismic risks for building structures, focusing on San Gabriel I Elementary School in General Mariano Alvarez, Cavite. Two structural models were developed using ETABS: a bare structure and a modified structure with Lead Rubber Bearings (LRB) as base isolators. Pushover Analysis and the Capacity Spectrum Method (CSM) were employed to assess the seismic performance of both models. Ground motion data from PHIVOLCS were processed using Seismosignal and Seismomatch for spectral matching based on UBC 1997. A capacity curve was generated from the pushover curve through FEMA 440 EL, showing the roof-level displacement and base shear. Performance points for the models were determined using response spectra, and fragility curves were developed to estimate the probability of collapse damage states. The analysis revealed that the X-axis of both models demonstrated greater strength than the Y-axis. The structure equipped with LRB showed superior seismic performance, with higher base shear capacity and reduced displacement compared to the bare structure. Damage states determined through CSM indicated that the LRB-enhanced model experienced significantly lower damage, ranging from "Moderate" to "Slight" along the X-axis and "Extensive" to "Slight to Moderate" along the Y-axis, compared to the bare structure.
