Risk assessment for performance-based engineering of wood residential construction subjected to wind hazard

摘要

Significant damage to residential construction from hurricane winds during the past decades has created a need to assess the risk of wood residential construction subjected to wind hazard. This paper presents a general methodology for assessing the probabilistic response (fragilities) of light-frame construction exposed to extreme wind. Performance goals and specific limit states are identified from a review of building performance during recent hurricanes in the United States. Limit state probabilities of structural systems for the performance levels identified above are developed as a function of 3-s gust wind speed, leading to a relation between limit state probabilities and wind speed.
