摘要
采用有限单元法对有吊车的单跨和双跨半刚接门式刚架进行了研究 ,分析中考虑了端板连接节点的半刚性和构件的几何非线性 ,探讨了节点半刚性对门式刚架内力和位移的影响 ,并给出了设计建议。
One-bay and two-bay semi-rigid portal frames with crane are analyzed with finite element method,and the effects of connections flexibility and members geometric nonlinearity are considered.Internal forces and deformations of portal frame with different rotational stiffness are discussed.Design method are presented in design practice.
