タイトル（英）：	Seismic Responses of Retrofitted Old RC Buildings
抄録（英）：	During the 1995 Hyogoken-Nanbu earthquake, many old concrete buildings suffered complete collapse at an intermediate story. When strong earthquakes happen in the future, such old buildings are very likely to suffer similar damages. They have to be retrofitted. In this study, seismic responses of the old buildings and those retrofitted using walls were analyzed and compared. Ten- story and five-story model buildings were analyzed. The major findings from the study are as follows: 1) if the old buildings are retrofitted in such manner that their base shear strength is more than or equal to 0.5 W (W: total weight), the inter-story drift demand remains within 1 % of the story height, and 2) a slight difference in the strength of added walls may occasionally result in large difference in the drift demand.
