摘要
文中提出一种新型方钢管柱-H型钢梁节点,采用T型钢通过高强螺栓将内置加劲部件的方钢管柱与H型钢梁连接.利用ABAQUS建立该节点有限元分析模型,通过对8个系列共29个节点的有限元分析,探讨了各类组件对节点性能的影响.结果表明:此节点为半刚性节点,具有良好延性;对拉螺栓间距、T型钢翼缘厚度等因素对节点静力性能影响较大;为此新节点在工程中的应用,提出了相关建议.
In this paper,a new type of connection between steel beams and square steel tube columns is put forward,i.e.SHS column and H-beam joint using high-strength bolted T-stubs and inner stiffeners.The finite element model of the connection is established using the general-purpose finite element software ABAQUS.A total of 29 connections in 8 series are analyzed,and the effects of connection components on the connection behavior are discussed.The results show that the connection is semi-rigid.The thickness of flange of the T-stub and the vertical spacing of through-bolts greatly influence the behavior of the connections.Some relevant suggestions for the connections in engineering application are raised.
