Predicting building damages caused by a destructive earthquake requires both earthquake ground motions evaluated for a prescribed scenario and vulnerability functions established by actual building damages. It is not easy to obtain accurate vulnerability functions because of insufficient number of observed data and spatial variability of strong motions. The purpose of this study is first to understand a relationship between the strength indices and then to establish vulnerability functions by using building models constructed by Nagato and Kawase (2001) with observed ground motions as input waves. Finally we verify these functions by comparing them with the observed damage during the 1995 Hyogo-ken Nanbu earthquake. We found that it would be better to use PGA^*PGV or JMA seismic intensity to construct vulnerability functions.
