Development of Fragility Functions based on Damage Levels of Wooden Buildings due to Earthquake

Abstract

To protect human lives from earthquake disaster is essential for disaster management. In the case of the 1995 Hanshin-Awaji earthquake disaster, especially, the building completely collapsed pattern without survival space was major killer.Therefore,it is important issue that revealing of how many buildings are facing to such risk and how to treat the risk against a post-earthquake disaster. In this paper, the fragility functions reflecting building damage levels with consideration of the building characteristics are developed based on the analysis of building damage patterns using photographic images. It will be a useful tool to estimate the occurrence of completely collapsed buildings.
