钢管结构法兰连接节点抗弯承载性能的有限元分析
Finite Element Analysis of Load-Carrying Properties of Flange-Plate Connections of Steel Tubular Structures under Bending Moment
摘要
Abstract
The domestic research on flexural capacity of flange-plate connections is almost blank, and related design methods are imperfect. For four basic kinds of flange-plate connections, nonlinear analysis was conducted with ANSYS, a general-purpose FEM software. The analytical results could meet the ones of corresponding experiments with respect to whole load-displacement curve, deformation and value of strain. It proved the reliability of the FEM models. Based on the models, the evolution law of in Von-Mises stress and contact pressure were studied. Some conclusions were drawn as follows: as the load increased, the flange plates showed obvious plastic properties; the pressure center of flange-plate could be considered as approximately constant in its designing process of flange-plate connections under bending moment.关键词
