| Research Abstract |
This study presents the seismic performance of existing buildings with low strength concrete less than 13. 5N/ mm^2. The experimental works using those members were performed. The effects of retrofitting were also investigated through the loading tests. The present equations could predict the maximum strength of those members and the jacketing method is effective to increase the seismic performance. It is found that epoxy resin injection was significantly effective to improve the bond characteristics of the plain round bars
