Abstract
2000.10.6 Tottori-ken seibu earthquake and 2001.3.24 Geiyo earthquake hit at Chugoku area, fortunately the extensive damage and economic losses did not occur though accelerations of lg or greater on the horizontal were recorded at several sites. Concerning reinforced concrete buildings, only one apartment building collapsed and one school building was severely damaged. A few numbers of buildings were moderately damaged. Objective of this study is to clarify the seismic performance of damaged RC buildings in two earthquakes using results of seismic evaluation method and data from the inspections. It is pointed out following results 1) it is difficult to evaluate the seismic performance only using seismic performance Indices Is. 2) it is necessary to consider concrete strength and defect sprung up at the constructions.
