Abstract

Earthquake resistance of RC column-steel beam (RCS) joints with simplified details were studied. Simplified details are necessary for large columns to improve the productivity and constructability. To strengthen the beam-column joint, the effects of transverse beams, studs, and U-cross ties were used. Four 2/3 scale interior RCS connections were tested under cyclic lateral loading. The specimens generally exhibited good deformation capacity exceeding 4.0% story drift ratio after yielding of both beam and beam-column joint. Ultimately, the specimens failed by shear mechanism of the joint panel. The test strengths were compared with the predictions of existing design methods.

대형기둥의 제작성과 시공성을 고려한 철근콘크리트기둥-강재보 접합부의 상세를 제안하였으며, 이를 적용한 접합부의 내진성능을 연구하였다. 접합부의 보강을 위하여, 교차보, 스터드, U형 타이 등의 상세를 고려하였다. 내진성능의 평가를 위해, 2/3 스케일의 대형내부접합부에 대하여 반복가력실험을 수행하였다. 실험체들은 층간변위비 4.0%를 넘는 우수한 변형능력을 발휘하였으며, 보의 항복과 접합부의 항복이 동시에 발생하였다. 최종적으로는, 접합부의 전단파괴로 하중이 감소하였다. 실험강도는 기존 설계모델과 비교되었다.
