초록

In this paper, an experimental study have been many studies on the joints of steel structure, for it has great influences on the safety of structures. Research on block shear rupture of the joint receiving pure tension have been done in foreign countries, but not in Korea. This study focuses on the propriety of block shear design code, according to limited state design criteria of steel structures recently established in Korea, by an experiment on the joint of angle tension members. The methods of this study were to compare other study results on block shear rupture mode and ultimate capacity, and to evaluate the propriety of the criteria design code. The result is that tension yield shear ruptures and shear yield tension ruptures happened at the joint, and the experimental rupture load was 15% higher than the capacity entered in the criteria design code. We conclude that it is necessary to revaluate the block shear design code presented by many studies on the limited state design criteria of steel structures.

강 구조물의 접합부는 구조물이 안전에 큰 영향을 미치는 부분으로서 이에 대한 연구는 많이 이루어지고 있으나 순수 인장력을 받는 접합부의 블록전단 파단에 대한 연구는 외국에서도 근래에 시작되었으며 현재 국내에서는 연구실적이 없는 상태이다. 본 연구는 최근 우리나라에서 제정된 강구조 한계상태설계기준에 따른 블록전단 산정식의 타당성을 인장력을 받는 ㄱ형강 접합부의 실험에 의하여 규명하고자 한다. 연구방법은 기존의 연구결과의 블록전단 파단형상 및 극한내력을 본 연구와 비교분석하고 기준 산정식의 합당성을 평가하였다. 실험결과 접합부는 2가지 형상, 인장항복 전단파단과 전단항복 인장파단이 일어났으며 실험 파단하중이 기준식에 의한 내력보다 약 15% 크게 나타나고 있어 앞으로 보다 많은 연구에 의해 강구조 한계상태 설계법의 블록전단 산정식에 대한 평가가 필요하다고 사료된다.
