초록

고강도 강의 경우 재료의 높은 항복비와 모재인성 부족으로 인해 휨 구조부재에 적용하기가 용이하지 않다. 고강도 강 휨재의 가장 큰 문제점 중 하나는 일반 연강접합부와 마찬가지로 보 단부의 취성파단이다. 연강접합부의 경우 부재의 보강 및 보 단부의 용접접근공 상세의 개량을 통하여 국내기준의 특수모멘트골조용 접합상세가 다수 개발된 바 있으나 고강도강 접합부에 대한 적용성 평가는 아직까지 미비한 실정이다. 본 연구는 국내에서 개발된 고강도 강(HSA800)을 적용한 기둥-보 접합부의 적용성 평가를 위한 초기단계의 연구이며 보 단부의 용접접근공 상세에 따른 고강도 강 접합부의 구조성능을 실험 및 해석적 방법을 통하여 고찰하였다.

For high-strength steel, it is difficult to be applied to flexible structural member because it have high yield ratio and low basic material's toughness. One of the great problems when using high-strength steel connections is the brittle fracture at the end of the beam member in common with general mild steel connections. In the cases of mild steel connections, it has be developed that special moment frame connection details by reinforcing structural member or improvement of welding access hole. But, it is incomplete at yet about applicability estimation of high-strength steel connections. This study is the initial step research for the applicability estimation of beam-to-column connections being applied to developed high-strength steel, HSA800. And, it studied about structural performance of the high-strength steel connections according to the details of welding access hole through full-scale test and analytical method.
