Abstract：As an important part of RCS structure, joint is prone to be damaged during earthquake. Based on the experimental study of the seismic performance of the RCS beamcolumn assemblies, it is found that the joint is not an ideal rigid connection, but a semi-rigid connection. To ascertain the mechanical and rotational characteristics of this semi-rigid connection, the influences of thickness of cylindrical steel plate, steel beam height, flange width-to-thickness ratio, column concrete strength, floor thickness and other structural measures on the flexural capacity and initial rotational stiffness of this connection under cyclic load are discussed systematically. In addition, based on the results from parameter analysis and sensitivity calculation, a four-segment multi-line curve model is proposed to describe the moment-rotation relationship of the semi-rigid connection. The simulation results are in good agreement with the test results, which can provides a reference for the design of RCS composite structure based on semi-rigid connection.
