Abstract

Adamson University buildings#x2019; age ranges from 10 years to 86 years. The structures#x2019; age can be one of the factors of their vulnerability to seismic hazard. Possibility of having different damages after the event of seismic activities can be measured through structural modeling and subjecting the latter to earthquake simulation. In the field of structural reliability, fragility analysis can be used in the assessment of structures. This type of analysis can be carried out by taking the structural performance using nonlinear analyses: Pushover Analysis and Time History Analysis. Five (5) buildings in Adamson University were analyzed and modeled in a structural analysis software based from the developed as-built plans with rebound hammer test results for the compressive strength of concrete. These structural models were subjected through a total of 22 ground motion data (from both Philippine and Japan), with each ground motion data normalized from 0.1g to 1.0g of peak ground acceleration (PGA). The result of fragility analysis has some limitations such as the use of asbuilt plan of each building assessed. The lowest probability of exceedance of 9% at a PGA of 0.4g as per National Structural Code of the Philippines specification is based from the fragility curve of FRC Building under a #x201C;Complete Damage#x201D; or damage rank of #x201C;As#x201D;. It is recommended in this study that proper handling of the results is a must since the study has limitations, especially, in the structural modeling. Also, for the administrators to use the result of the study, exposure to seminars and trainings of the staffs in the physical and facility office is a must so that they are aware of the basic to high-end structural assessment tools and methodologies that can be applied to the rest of the school buildings.
