Abstract

A double split tee connection is used as a connection that is suitable for ordinary moment frames or special moment frames according to the combination of variables of the thickness of the T-stub flange and the gauge distance of the high-strength bolts. In order to demonstrate safe structural behavior, a double split tee connection must meet the requirements for inter-story drift angles and the moment of connection, as defined in the Korea Building Code-Structural. In order to determine whether the these requirements are met, it is necessary to predict rotational stiffness and the ultimate plastic moment of the connection. Therefore, this study primarily aimed to propose an analytical model for predicting the rotational stiffness of a double split tee connection under a static load. Toward this end, a three-dimensional, non-linear finite element analysis was carried out. Then, the applicability of the proposed model was verified after comparing the test results of this study with other studies.

상 하부 스플릿 T 접합부는 T-stub의 두께, 고력볼트 게이지 거리 등의 주요 변수 조합에 따라서 보통모멘트골조 혹은 특수모멘트골조에 적합한 접합부로 사용된다. 상 하부 스플릿 T 접합부가 안전한 구조거동을 발휘하기 위해서는 건축구조기준에서 규정한 층간변위각 및 접합부모멘트에 대한 요구사항을 만족하여야 한다. 이러한 요구사항 조건의 충족여부를 파악하기 위해서는 접합부의 회전강성 및 한계소성모멘트에 대한 예측이 필수적이다. 따라서 이 연구는 일차적으로 정적하중을 받는 상 하부 스플릿 T 접합부의 회전강성 예측을 위한 해석모델 제안을 위하여 진행하고자 한다. 이를 위하여 3차원 비선형 유한요소해석을 수행하였다. 제안한 해석모델의 적용 적합성은 기존의 해석모델 및 실험결과와 비교 검토하여 입증하였다.
