Abstract：Roof coverings on the building roof are prone to damage in strong winds and their loss may cause larger damage to the building interior due to rainwater penetration. Hence this paper presents a probabilistic damage estimation procedure to predict roof covering damage in strong winds based on the wind pressure coefficient data collected from the wind tunnel test at the University of Western Ontario. Firstly, the wind tunnel test and the experimental data are briefly introduced. Secondly, Hermite polynomial model is used to estimate the probability density distribution of wind pressure coefficient for each measuring point. Furthermore, the translation process method is adopted to evaluate the probability distribution function of corresponding peak wind pressure coefficient. Finally, with the asphalt shingle as the example, the failure probability for each shingle and the damage ratio for the entire roof are determined, including the cases with and without consideration of the variability of mean wind speed.
