각형강관 기둥H형강 두계중복형 접합부에 관한 연구 ( Beam-to-Column Connections with Square Section Steel Members for Column )

The objestive of this study is to investigate the strength and the stiffness members of beam-to-column connections in which square hollow section members are used for columns. Ther are three types in already established beam-to-column connections with wquare section coumn for rigid joints, that is, diaphragm penetrated type, inside diaphragm type and outside diaphragm type have been developed till now. But it is difficult and is complicate to apply to high rise buildings because of installation of diaphragms under the condition of our country. In this paper the new types of beam-to-column connection is suggested when wquare hollow section members are used for columns. Bending tests are carried out about new suggested type and initial stiffness is investigated.
