Abstract

A study was conducted to secure structural performance as well as improve workability by improving the reinforcement details of special shear wall and coupling beams. Based on the specimen in which the existing diagonal bundle reinforcement and shear reinforcement were placed, the specimens replaced with thick diagonal reinforcing bars and the specimens replaced with horizontal reinforcing bars were selected as variables. As a result of the experiment, the specimen, which replaced the existing diagonal reinforcement with a thick-diameter reinforcement, showed a similar behavior to that of the basic specimen, and it was evaluated that it can be applied as an alternative to the details.

본 연구에서는 특수 전단벽 연결보의 배근 상세를 개선하여 구조 성능의 확보는 물론 시공성을 개선한 연구를 진행하였다. 기존 대각선 다발철근과 전단 보강근을 배근한 실험체를 기본으로 이를 굵은 대각철근으로 교체한 실험체, 수평 보강근으로 교체한 실험체를 변수로 선정하였다. 실험결과 기존 대각보강근을 굵은 직경의 철근으로 대체한 실험체가 기본 실험체와 유사한 거동을 보여 복잡합 연결보 보강 상세의 대안으로 적용 가능한 것으로 평가되었다.
