초록

상·하부 스플릿 T 접합부는 부분강접 접합부의 한 형태로 접합부에 사용된 T-stub의 두께 및 고력볼트 게이지 거리 변화에 따라서 충분한 휨강도를 갖는다. 뿐만 아니라 상·하부 스플릿 T 접합부는 강재의 종류, 보 및 기둥의 규격, 접합부 형상 등의 조합에 의하여 보통모멘트골조 혹은 특수모멘트골조에 적용 가능한 충분한 연성능력을 갖는 내진접합부로 설계 및 시공 된다. 그러나 이러한 상·하부 스플릿 T 접합부에 대한 국내의 연구는 아직 미흡한 상황이며 적합한 설계식의 제안도 이루어지고 있지 않다. 그러므로 상·하부 스플릿 T 접합부의 국내 적용을 위해서는 많은 실험 및 해석적 연구가 필요한 상황이다. 따라서 이 연구는 FEMA의 상·하부 스플릿 T 접합부에 대한 설계식을 검토하고 국내의 적용 가능성을 타진하고자 진행하였다.

Abstract

The double split Tee connection, a type of full strength-partially restrained connection, has adequate flexural strength according to the changes in the thickness of the T-stub flange and the gauge distance of the high-strength bolts. Moreover, the double split Tee connection is designed and constructed with seismic connections that have enough ductility capacity applicable to ordinary moment frame and special moment frame by grade of steel, size of beam and column and geometric connection shape. However, such a domestic research and a proposal of a suitable design formula about the double split Tee connection are insufficient. Thus, many experimental and analytical studies are in need for the domestic application of the double split Tee connection. Therefore, this study aimed to examine and suggest feasibility of a design formula of the double split Tee connection of FEMA.
