We propose a method to evaluate vulnerability functions based on earthquake response analysis in consideration of not only dispersions of structural strength but also dispersions of ductility capacity. Vulnerability functions, which show the relationship between the ratio of damaged buildings and the peak ground velocity, calculated using this method indicate good correspondence with vulnerability functions obtained from the data of damaged buildings during the 1995 Hyogo-Ken-Nambu earthquake. The data of wooden buildings and reinforced concrete buildings are focused in this paper. This method is practically useful for examining the building damage ratio considering the characteristics of building structure performance, ductility capacity, and seismic ground motion.
