摘　　要：针对以往钢管混凝土柱梁节点受力性能及应用中的缺陷,提出梁通柱断式新型加强环节点型式。通过ANSYS有限元软件分析其受力性能、节点破坏形态、承载力以及节点各参数对其约束刚度的影响,证明其能够实现“强柱弱梁”和塑性铰形成于环与梁交角处的抗震设计理念,具有较好的适用性。Aim at the shortcomings of concrete filled steel tubular column-beams loading behavior and application,a new type of beam continual and column discontinued horizontal joint model is presented.which are analyzed by ANSYS nonlinear finite element method,such as the mechanics behavior,the failure modes,the carrying capacity and the various element influence on rigidity,it is obvious that the seismic design concepts of the strong column-weak beam and plastic hinge occurs to loop associate with beam,which will certainly has better applicability in engineering practice.
