This paper presents a fragility assessment for roof sheathing in light-frame wood constructions built in high wind regions. A fragility methodology is developed to assess the performance of roof sheathing subjected to wind-induced building pressures. The goal of this study is to develop a fragility model for roof sheathing system using available resistance test data, recently developed wind load statistics and building code. A typical baseline building considering different geographic locations

Fragilities of the baseline building considering three different levels of damages are developed as a function of 3 second gust wind speed. The fragility methodology described in this paper can be used to estimate physical vulnerability and financial loss of light-frame wood construction in high wind regions.
