더블 H형강 보 스트럿(DBS)을 이용한 지하 수평구조 보-기둥 접합부 구조거동에 대한 실험연구

The purpose of this study is to verify structural performance of joint with # type beam - column at DBS system which has the advantages of wide construction area and use horizontal strut beams as the permanent member of structure. Test specimen have been tested with variables of number of stud, thickness and shape of shear plate and distance between column and # type girder. The results shows that shear plate mainly affected at RC and RCST type specimen. The ultimate strength is higher as the distance of # type girder - column is shorter. All of test results show higher capacity than design calculation because of concrete confinement effect of steel beam.
