Abstract

H형강 기둥에 대한 신형상 약축접합부를 개발하여 단조가력실험을 통해 구조성능평가에 관한 연구를 수행하였으며, 선행연구결과를 바탕으로 본 연구는 시공성을 고려한 신형상 약축접합부의 내진성능을 평가하기 위해 반복가력실험을 실시하였다. 신형상 약축접합부는 접합개소 및 용접량이 적고 접합상세가 단순하며, 접합부에 작용하는 힘의 흐름이 명확하다는 장점이 있다. 이에 따라 H형강 기둥플랜지와 보 단부의 겹침길이를 실험변수로 한 신형상 약축접합부(WPL-WK-FC2, WPL-WK-FC3)와 건축강구조 표준접합상세지침에 근거한 표준 약축접합부(HH-WK-FC4) 총 3개의 실험체를 실물대 사이즈(Full-scale)로 제작하였다. 실험결과, 신형상 약축접합부는 0.04 rad 이상의 층간변위각에서 보 소성모멘트(<TEX>$M_P$</TEX>)의 80%이상을 유지하는 특수모멘트골조(SMF)의 내진성능을 확보하였으며, H형강 기둥플랜지와 보 단부의 겹침길이가 50 mm 이상이면 시공성 뿐만 아니라 구조적으로 우수한 것으로 나타났다. H-section steel column new shape weak-axis was developed and performed through monotonic loading test regarding basic structural performance evaluation. In this study cyclic loading test was followed up in order to evaluate seismic performance through the full-scale of new shape weak-axis connection for constructabilitiy. New shape weak-axis connection has a simple shape with the less spot of welding points, and it has advantage about showing the obvious flow of strength in connection points. Therefore, three specimens are built for the variables which are overlap length of beam-end and column flange. As the result, New shape of weak-axis connection is appeared special Moment Frame(SMF) and have excellent structural performance and constructablility when the parameter is over 50 mm.
