RESILIENCY OF A FOUR-STOREY STANDARD SCHOOL BUILDING USING THE REDI FRAMEWORK
Keywords:Resilient buildings, Resilience-based design, PACT, Loss assessment, REDi rating
Public school buildings in the Philippines are built with a code-based design philosophy, wherein the life safety of the occupants is the sole performance objective. While the loss of life is the primary consideration for design, other losses such as cost of repair or replacement and service losses are to be expected after an earthquake. The 2017 Surigao Earthquake damaged 47 schools and caused a 10-day suspension of classes. Three years after the 2013 Bohol Earthquake, 279 classrooms from 696 schools are still under construction. A resilience-based design philosophy takes into consideration safety and other losses including recovery. To assess the resilience of a structure, a resilience-based seismic assessment methodology was adopted after the REDi Framework. Other tools utilized for the seismic assessment were the FEMA P-58, their accompanying software PACT, as well as SeismoStruct. It consists of the identification of losses in terms of cost and time, as well as the evaluation of proper building management and design practices. As a pilot study, a four-storey twelve-classroom template was assessed for seismic resilience. Numerical simulations and analysis showed that the structure was not resilient in ambient and building resilience.
