Development of Fragility Curves for Buildings Based on Damage Survey Data of a Local Government After the 1995 Hyogoken-Nanbu Earthquake

This paper presents fragility curves for buildings based on damage data due to the 1995 Hyogoken-Nanbu Earthquake. The fragility curves in terms of the structural type and construction period were constructed using the building damage data of Nada Ward surveyed by Kobe City for the purpose of property tax reduction. It was also demonstrated that the number of damaged buildings in Nada Ward estimated by the fragility curves fits the actual damage by the earthquake. The fragility curves thus obtained may be useful for damage assessments of buildings in Japan.
