정적 및 피로하중을 받는 고장력볼트 인장이음부의 구조거동에 관한 실험적 연구

When a steel bridge is connected, usually friction type joint is used for high strength bolted joints. However, sometimes tension type joint is better than friction type joint. Though, it is partially applied on building structures, and is not possible to apply it on the bridge structures, because of design specification absence and lack of research data about high strength bolt tension type joints. Therefore, this study is to suggest basic data for investigation of high strength bolt tension type joint's fundamental mechanical behaviour through the static tensile test and fatigue test about T connection of steel members that focus on the short bolt type of high strength bolt tension type joint. The influences about the bolt diameter differences on the same flange thickness were examined. On the other hand, different yield load on bolts through the failure mode was recognized even the same bolts were used when influences on the flanges with different thickness and same diameter of bolts were examined.
