각형강관 접합부의 보 형상에 따른 강성 및 내력 ( Stiffness and Strength depend on Beam Shape in Box Column Connections )

The objective of this study is to investigate the strength and stiffness of beam-to-column connection in which square section members are used. The initial stiffness of the connections is studied by using finite element method. The yield line theory is applied to assess the strength of the connections. The results of analysis is compared with the previous test results. The parametric study for the initial stiffness of beam -to-column connections is conducted by changing the ratio Bf/D.A practical equation for strength of a connection is suggested by using the yield line theory.
