钢管混凝土柱-钢梁隔板贯通节点内孔径分析

Nonlinear FEM Analysis of the Size of Inner Pore of Concrete Filled Steel Tube Column to RBS Beam Connections with Crossing Diaphragm

采用有限元软件ANSYS对钢管混凝土柱-翼缘削弱钢梁隔板贯通节点的内孔径大小进行分析。在参照有关文献推荐标准的基础上,验证该节点内孔径的取值范围。结果表明:当内孔径大小范围D-bf≤d≤bd-bf时对节点的受力性能影响不大。但当内孔径继续增大,节点在循环荷载下会提前破坏。

This paper focuses on the parameters analysis ofinner pore ofconcrete fiUed steel tube （CFST） column to RBS beam connections with crossing diaphragm using ANSYS. On the basis of relevant documents recommendation, it verified the size range offinnerprerrespndsthende.Theresutsshwsthat：whentheinnerpesizerangefromD-bf〈 d〈 bd-bf, it has little effect on the mechanical properties of the node s.But when the inner pole size c ontinuosly increased.the node would be destroyed in advance.
