Vulnerability functions using seismic diagnosis data extended by equivalent linear models

It is important to establish an accurate vulnerability function to estimate seismic damage. The purpose of this study is to expand vulnerability functions of wooden buildings using seismic diagnosis data based on equivalent linear models. The vulnerability functions consider characteristics of the region such as ground and building characteristics. The paper describes a method to calculate ratio of building damage in a region. The accuracy of the method is verified using the damage data of the Great Hanshin-Awaji Earthquake Disaster.
