Abstract:
Earthquakes are considered one of the natural disasters experienced here in the Philippines. Accordingly, the highest magnitude ever recorded in Zamboanga Peninsula was 1976 with magnitude of 7.9 earthquake almost 8,000 lives were affected to this kind of disaster. This approximately reached 7,000 kilometers of coastline bordering the sea in Mindanao, the Moro Gulf, which affecting the City of Zamboanga. This study investigates the seismic performance of a proposed 15-storey building in Pasobolong, Zamboanga City, Philippines, incorporating a pendulum-tuned mass damper (PTMD) to mitigate earthquake-induced displacements. Given the Philippines' vulnerability to seismic activities, the study aims to enhance the safety and structural integrity of high-rise buildings in earthquake-prone areas. The researchers conducted a visual investigation and data collection from the ongoing construction project managed by Metro Stonerich Corporation, focusing on essential soil profiles and building design parameters. Employing SAP2000 software, the study evaluates the displacement responses of two models: one featuring a PTMD and the other lacking it. The results indicate that the building equipped with a PTMD experiences significantly lower displacement during seismic events, demonstrating its effectiveness in reducing structural movement and enhancing safety. Statistical analysis, including paired t-tests, confirms a substantial difference in displacement between the two models, leading to the rejection of the null hypothesis. The findings underscore the importance of incorporating innovative damping solutions in high-rise constructions to improve resilience against earthquakes, benefiting stakeholders such as civil engineers, investors, academic institutions, and the broader community.
