Abstract

This study deals with a new database of building foundation damages due to 1995 Hyogoken-Nanbu Earthquake and a seismic index of building foundation based on the database. The new database is restructured by adding new factor of seismic intensity and liquefaction potential at the site, to the published database of foundation damages after the earthquake. The proposed seismic index of building foundation is calculated by simple factors and correlates to seismic damage level of building foundation.
