Abstract

An experimental study was performed to evaluate the seismic performance of beam-column connections using 600 MPa re-bars for beam flexural reinforcement. Three full scale specimens of interior beam-column connection and two specimens of exterior beam-column connection were tested under cyclic loading. The specimens were designed to satisfy the requirements of Special Moment Frame according to current design code. The structural performance of the specimens with 600 MPa re-bar were compared with that of the specimen with 400 MPa re-bars. The test results showed that bond-slip increased in the beam-column joint. However, the load-carrying capacity, deformation capacity, and energy dissipation capacity of the specimens with 600 MPa re-bar were comparable to those of the specimens with 400 MPa re-bars.

보 휨 철근으로 600 MPa 철근을 사용한 콘크리트 보-기둥 접합부의 내진성능을 평가하기 위하여 실험 연구를 수행하였다. 세 개의 내부 보-기둥 접합부 실험체와 두 개의 외부 보-기둥 접합부 실험체를 주기하중 하에서 실험하였다. 실험체는 현행 기준에 따라 특수 모멘트 골조로 설계하였다. 600 MPa 철근을 사용한 실험체의 구조 성능을 400 MPa 철근을 사용한 실험체의 구조 성능과 비교하였다. 실험 결과 600 MPa 철근을 사용한 실험체에서 보-기둥 접합부에서 부착 미끄러짐이 증가하였으나, 하중 재하 능력과 변형 능력, 에너지 소산 능력이 우수한 것으로 나타났다.
