兵庫県南部地震における明石市の建物被害データに基づく地震動強度分布の推定

抄録

The number of strong motion records in the 1995 Hyogoken-Nanbu Earthquake was not large enough to estimate the detailed spatial distribution of strong ground motion. Hence additional information, e.g., building damage ratio, results of questionnaire survey, is often employed for the estimation of strong motion distribution. This paper analyzed the building damage data in Akashi City, in which the structural type and construction period of each building are included. Using the fragility curves developed for Nada Ward of Kobe City and the building damage data for Akashi City, the strong motion distribution in Akashi City was estimated and the results were compared with other research results.
