Abstract
In order to evaluate the building damage in the 1995 Hyogoken-Nanbu Earthquake, it is important to estimate the distribution of strong ground motion. We have estimated the ground motion distribution in Hanshin area using the recorded ground motion and building damage data compiled by Building Research Institute (BRI). However, the estimated strong motion distribution might be affected by the construction period of buildings in each district and the distribution was not estimated in some areas without enough number of buildings. Hence in this study, the ground motion distribution was re-estimated using the building damage data surveyed by Nishinomiya City, which have detailed building information. Using the re-estimated distribution, fragility curves considering detailed building information can be developed.
