Wind Fragility Development for Roof Sheathing System of Light-Frame Wood Structure

This paper presents a fragility assessment for roof sheathing in light-frame wood constructions built in high wind regions. A fra-gility 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 is investigated using a Mote Carlo simulation method. 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 vul
