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。
The finite element method is used to study the single-span and double-span semi-rigid portal frame with crane. The semi-rigid connection and the geometric nonlinearity of the members are considered in the analysis. Frame internal force and displacement, and gives the design proposal.
