摘　　要：蜂窝状钢骨混凝土异形柱框架体系是一种很适合于当今钢结构住宅建筑的新型结构体系,其梁柱节点是这一结构体系的关键部位之一。为了探讨蜂窝状钢骨混凝土十字形柱-钢梁连接节点的受力性能与变形特性,文章运用ANSYS有限元分析软件,分析轴压比、配箍率、混凝土强度、型钢强度、节点域型钢腹板高厚比、钢骨腹板开孔至节点域横向加劲肋间的距离等主要参数对节点承载力的影响及其规律,并给出了该类节点承载力计算公式中相应参数的合理取值与设计建议,可为后续研究和工程应用提供参考。In the modern times,honeycomb steel-reinforced concrete（SRC） special-shaped column frame system especially suits steel structure resident house.The column-beam joint is the key component of this system.In order to explore the stress and deformation characteristic of honeycomb SRC crossed-shaped column-steel beam joint,this paper uses ANSYS software to analysis.It studies some effecting factors and laws,such as axial compression ratio,the hooped stirrup ratio,the concrete strength,the steel strength,steel web panel height-thickness of the joint,the distance between the hole of the steel skeleton and transverse stiffener and so on.It suggests rational value of corresponding parameters for bearing capacity formula of this kind of joint.In the end,it gives some design suggestions of this component to provide a reference for further research and application.
