Abstract

Earthquakes had always been one of the most devastating disasters. Aside from the structural damage it brings, casualties have always been inevitable. With the goal of minimizing casualties brought by structural failure in case of an earthquake, studies have been conducted. In a previous study investigating the seismic risk of UPLB buildings, the UHS Main Building-an 8 meter tall, two-storey reinforced concrete building with plan irregularity built in 1971-was found to be the second most at-risk building based on seismic exposure, hazard, and vulnerability. Because of this, a nonlinear static analysis or pushover analysis was performed on UHS Main Building. Two models were created: a fixed based and a flexible based, and in accounting material nonlinearity, finite hinge zone models were used. Pushover curves were generated for each model, and the curves with the largest drift/displacement were used to assess the building's structural performance level which is expected to be Immediate Occupancy or very limited structural damage. In the fixed based model, the columns from the foundation until the second floor, while in the flexible based model, the columns from the ground floor until the second floor exceeded the Immediate Occupancy limit state. These columns make the UHS Main Building noncompliant to its expected performance level, and should be subjected to retrofitting.
