A framework to calculate a quantitative measure of seismic resilience using the Endurance Time (ET) method is introduced. ET method is a response-history based analysis procedure where structures are subjected to gradually intensifying dynamic excitations and their performance is assessed based on their response at di erent excitation levels, reducing the required computational e ort. First, a prototype hospital building is optimally designed through three distinct design philosophies: prescriptive design code, performance based design criteria, and value based seismic design method. In value based design method, the design sections of structural elements are assumed as optimization parameters and a design with minimum total cost during its lifespan is sought. For each candidate design, the damages due to probable earthquakes are estimated by the ET method and the expected cost of damages is calculated using Life Cycle Cost Analysis (LCCA). Next, the resilience of each design in continuous range of hazard intensities is compared with that of others, introducing \Resilience Curve". Although the optimization objectives in design process are not based on resiliency measures, the value based design shows the best resiliency in the case of seismic hazards. This methodology and potential bene ts when considering the need for moving towards more resilient cities are discussed.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
