Research on Ultimate Moment of Top-and-Seat Angle Connections in Semi-Rigid Steel Frames

Abstract:

Top-and-seat angle connection is a type of semi-rigid connection, usually used in steel frame. The stress distribution and the formation of plastic hinge of connection were analyzed using ANSYS. According to the results of FEM analysis, theoretical model of the top angle was proposed. And then, the ultimate moment formula of connection was proposed based on the Mises criterion. For verifying the correction of ultimate moment formula, 13 FEM models were built and ultimate moments were calculated. The formula proposed by the article agreed well with the results of the FEM analysis. And it proves that, the ultimate moment formula of top-and-seat angle semi-rigid connection can be used in the design.
