초록

병렬전단벽시스템은 경제적이고 효율적인 구조시스템이지만, 연결보의 복잡한 철근상세가 요구된다. 이를 보완하고자 ACI-318에서는 개선된 철근상세를 제안하고 있지만 과도한 횡보강근으로 현장 적용에 어려움이 따른다. 이 연구에서는 횡보강 철근량을 감소시킨 대각철근을 갖는 HPFRCC 연결보 상세를 제안하고, 형상비 2.0 실험체를 통해 현행 기준에 만족하는 대각철근을 갖는 철근콘크리트 연결보와 이력거동을 비교 평가하였다. 그 결과, HPFRCC의 횡구속 효과를 확인하였고, 횡구속 철근을 기준의 1/2로 배근하고 HPFRCC로 보강한 연결보는 현행기준에 따른 연결보와 유사한 내진성능을 보였다. HPFRCC 보강을 통해 대각보강된 철근콘크리트 연결보의 횡구속 철근량을 감소시킴으로써 철근상세의 단순화가 가능할 것으로 판단된다.

Coupled shear walls can provide an efficient structural system to resist lateral force. However, the reinforcement detail for diagonally reinforced coupling beams required by ACI-318 often causes the difficulties in construction due to the reinforcement congestion and interference among reinforcement. This paper is to evaluate cyclic behavior of High-Performance Fiber-Reinforced Cement Composite (HPFRCC) coupling beams having reduced transverse reinforcement around the beam perimeter. Experimental test was conducted using three specimens having a beam aspect ratio 2.0. Test results showed that HPFRCC coupling beams with half of transverse reinforcement required by ACI-318 provided similar energy dissipation capacities compared with the coupling beams having reinforcement satisfy the requirement of ACI-318.
