고인성 보강재를 사용한 철근콘크리트 구조물의 내진보강

Many existing RC Buildings were built before the seismic code was established, they need seismic retrofit performance. In this study, presents the evaluations of seismic performance and displacement ductility for two type RC Frames : existing RC frame without SRF(Super Reinforcement with Flexibility) and RC frames strengthened with SRF.
