钢框架梁柱连接节点转动刚度试验研究
Experimental study on rotational stiffness of steel frame beam-column connections
摘要
Abstract
In order to investigate the rotational stiffness and the failure mode of beam-column connections,common types of connections,including full welded connection,extended end-plate bolted connection,T-stub bolted connection,top-seat and web angle bolted connection,were tested under monotonic loading.Experimental results show that the rotation angles of all specimens exceed 0.05 rad,and the plastic rotation angles exceed 0.04 rad.The shear deformation of panel zone is relatively large,especially for welded joints,leading to the significantly reduced rotational stiffness of connections.If the connection is strong enough,the frame beam can form plastic hinge before the connection fails.Otherwise,connectors can be easily damaged due to excessive deformation.Based on the classification and analysis of test data,the total rotation angle of a beam-column connection can be divided into two parts,the rotation angle of panel zone and the rotation angle of connectors.The simplified calculation method of the elastic rotational stiffness and angle of common types of connections are presented and compared with the test results.关键词
