摘要：

提出由投影面为四边形的六杆四面体所集合组成的双曲面网壳，可以用作大型钢结构冷却塔的主体结构. 探讨该网壳形式的构形，它构造简单，兼具单层网壳与双层网壳的特性. 总结了正交正放与正交斜放2种基本布置形式，对正交正放的双曲面冷却塔网壳进行静力、线性与非线性稳定分析. 结果显示，该网壳内力分布合理，上、下弦杆及顶部环杆在受力上起到不同的作用，分工明确；线性与非线性稳定性能良好，且结构对于缺陷不敏感；网壳具有较好的经济指标，容易实现工业化生产与装配化施工.

Abstract:

A hyperboloidal lattice shell composed of six-bar tetrahedral units was proposed, which can be used as the main structure of a large steel cooling tower. The configuration of the lattice shell was discussed. It is simply formed and has both the characteristics of the single-layer lattice shell and double-layer lattice shell. Two arrangements of units as known as orthogonal ortho-laid type and orthogonal diagonal-laid type were summarized. Static, linear and nonlinear stability analysis was conducted in an orthogonal ortho-laid lattice shell. Results show that the lattice shell has clear static behavior and appropriate distribution of inner force. The structure has satisfying performance on both linear and nonlinear stability, which are not sensitive to structural imperfection. This lattice shell system has highly economical efficiency and can be easily constructed.
Key words: six-bar tetrahedral units    hyperboloidal lattice shell    steel cooling tower    structural configuration    static analysis    stability behavior
