상·하부 ㄱ형강 접합부의 접합부실험을 통한 초기회전강성 평가

초록

Studies indicate that top and seat angle connections, based on the combination of the variables mentioned, not only have shear resisting capacity, but can also have adequate bending moment resisting capacity. Therefore, a close investigation of the relationship between the rotational stiffness of the connection and the geometric variables ′ of the angle steel that forms a top and seat angle connection, will greatly aid in the design and installation of such connections. Accordingly, this study was performed to select top and seat angle connections having the same beam-column stiff ratio. The geometric variable values of ′ of the angle steel were varied, while the changes in shear strength as well as changes in the initial rotational stiffness were identified. For this purpose, two top and seat angle connection test specimens were prepared to test the connection.
