초록

본 논문에서는 리브로 보강된 철골 모멘트 접합부의 내진설계법 정립을 위한 등가 스트럿 모델을 제시하였다. 리브 보강 접합부의 응력전달 메커니즘은 고전 휨이론에 의한 예측과는 전혀 다르며, 리브는 리브의 기울기 방향으로 스트럿 거동을 보임을 유한요소해석에 의해 밝혔다. 리브를 스트럿 요소로 파악하여 리브 접합부의 실용설계에 활용될 수 있는 등가 스트럿 모델링 방안을 제시하였다.

This paper presents an equivalent strut model for seismic design of steel moment connections reinforced with ribs. It is shown from the finite element analysis results that the force transfer mechanism in the rib connections is completely different from that predicted by the classical beam theory and a clear strut action in the ribs does exist. By treating the rib as a strut, an equivalent strut model that could be used as the basis of a practical design procedure is proposed.
