Fragility Assessment of Light-Frame Wood Construction Subjected to Wind and Earthquake Hazards 1 2 3 4 Bruce R. Ellingwood, M.ASCE ; David V. Rosowsky, M.ASCE ; Yue Li, S.M.ASCE ; and Jun Hee Kim Abstract: A fragility analysis methodology is developed for assessing the response of light-frame wood construction exposed to stipulated extreme windstorms and earthquakes. Performance goals and limit states structural and nonstructural are identified from a . d review of the performance of residential construction during recent hurricanes and earthquakes in the United States. Advanced numerical e v r e modeling tools provide a computational platform for risk analysis of light-frame wood building structural systems. The analysis is s e r s demonstrated for selected common building configurations and construction defined, e.g., by roof sheathing, truss spacing, and roof or t h g shear wall nailing patterns. Limit state probabilities of structural systems for the performance levels identified above are developed as a i r l l function of 3-s gust wind speed hurricanes and spectral acceleration earthquakes, leading to a relation between limit state probabilities a ; y l and the hazard stipulated in ASCE Standard 7, “Minimum design loads for buildings and other structures.” n o e s DOI: 10.1061/ASCE0733130:121921 u l a n o CE Database subject headings: Building codes; Earthquakes; Hurricanes; Probability; Timber construction; Wooden structures; s r e p Framed structures. r o F .
