Abstract1   본 연구에서는 기존 RC구조물의 내진보강을 위한 유공강판의 횡력저항능력 특성에 관한 실험적 연구를 진행하였다. 실험체는 형상비, 유공비율, 유공직경 및 유공스트립 간격을 주요 변수로 구성하였다. 하중은 변위 제어를 통해 층간변위비 3.5%까지 반복 가력하였다. 유공강판 실험체는 최대 강도가 층간변위비 0.5% 이내에서 발현되었으며 층간변위비가 3.5%에 도달할때까지 내력이 유지되었다. 실험 결과를 통해 유공강판에 대한 수정강도예측식을 제안하였으며 유공강판을 이용한 RC 구조물의 내진보강 성능을 평가하기 위한 설계 과정을 제시하였다.
Abstract2   In this study, an experimental research was performed to find the characteristics of the lateral load resistance of perforated steel plates which could be developed to retrofit existing RC framed buildings. The Specimens are tested with variables such as aspect ratio of plate, the ratio of perforation area, and the ratio of perforated diameter to strip which is more than 0.6. The lateral load was applied with displacement control until to reach 3.5% drift ratio. Through the experimental results, it was shown that the maximum strength of all specimens were reached at around 0.5% drift ratio and maintained until 3.5% drift ratio. From results, the modified strength prediction formula was derived with the variable ratio of the perforated diameter to strip. To evaluate seismic retrofit performance of RC frames using perforated steel plate, a simple design process was presented.
