| 中文摘要: |
| 合理确定斜拉索的预张力是斜拉空间网格结构成败的关键，提出一种适用于半刚性结构的静力平衡法线性迭代优化方法。通过对灵武体育中心体育场屋盖斜拉索张力优化分析，获得{N3}=(1+0.3)N为优化预张力，结构最大竖向位移为跨度的1/718，各杆件应力/强度比基本在0.8以内。 |

| Reasonable determination of the pre tension in cables is the key point to the success of cable stayed spatial grid structure. This paper presents a linear iterative optimization method of static equilibrium method suitable for semi rigid structure. By analyzing and optimizing the tension in the roof cables of Lingwu Sports Center Stadium, this paper obtains the conclusion that {N3}=(1+0.3)N is the optimized pretension of the cables, and under this circumstance, the maximum vertical displacement of the structure is 1/718 of the span and the stress / strength of each rod is less than 0.8. |
