板锥网壳结构是一种受力性能合理,技术经济效益良好的新型空间结构形式。本文考虑板片和杆件协同工作时的几何非线性,采用弧长法跟踪荷载—位移全过程平衡路径,对板锥网壳结构的极限承载力性能进行全过程非线性跟踪分析,确定其稳定性能及杆件和锥体单元板件屈服顺序,对板锥网壳结构的破坏机理和极限承载力等问题进行了研究,并与普通双层网壳结构进行了比较,得出了可应用于工程实践的重要结论。
Plate cone reticulated shell structure is a new type of space structure with reasonable performance and good technical and economic benefits. In this paper, considering the geometric nonlinearity when the plates and rods work together, the arc-length method is used to track the equilibrium path of the whole process of load-displacement. The whole process of the ultimate bearing capacity of the cone- Performance and the order of yield of the rod and cone elements, the failure mechanism and ultimate bearing capacity of the cone-shell reticulated shell were studied and compared with the conventional double-layer reticulated shell structure, An important conclusion of engineering practice.
