法兰连接节点抗弯承载性能的研究在国内外几乎是空白
相关的设计方法也不成熟.对4种形式的法兰连接节点
采用通用有限元软件AN SY S
进行了其在弯矩作用下的非线性分析计算.在整体荷载-位移曲线、变形结果和应变结果等三方面
计算结果均与相应的试验结果吻合良好
验证了有限元模型的可靠性.利用此有限元模型
分析了法兰盘V on-M ises应力和接触应力的发展规律.结果表明:随着荷载的增加
法兰盘表现出了明显的塑性发展特征;在进行法兰连接抗弯设计时
可以认为法兰盘压力中心的位置近似恒定.
The domestic research on flexural capacity of flangeplate 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.
