Development of fragility curves for seismic vulnerability assessment: The case of Philippine General Hospital Spine Building

The Philippine General Hospital (PGH) is a tertiary hospital in Ermita, Manila, that was founded on August 17, 1907. It adheres to the philosophy of providing all Filipinos with internationally competitive, cost-effective, compassionate, and accessible health care. It was recently one of the COVID-1...

Furthermore, for 0.4g PGA, the calculated highest likelihood of exceedance in the 'collapse damage' condition was 5.24 percent, with no results above 10%, implying that the PGH Spine Building complies with the NSCP seismic requirement for structures located in Seismic Zone 4. As a result, an adequate retrofitting strategy is not required for the PGH Spine Building. 2022-12-01T08:00:00Z text https://animorepository.dlsu.edu.ph/faculty_research/11762 Faculty Research Work Animo Repository Earthquake hazard analysis—Philippines Hospital buildings—Earthquake effects—Philippines Structural Engineering
