| 摘 要： | 基于本建立的拉索式空间预应力钢桁架优化分析的一般计算模型，对几种不同结构方案的预应力立体钢桁架进行了优化分析，得到了相应结构的整体刚度参数-最大挠跨比与钢索预拉力、钢索截面尺寸及总用钢量等参数的变化关系（用一组图表表示），并讨论了不同结构方案的用钢量与高跨比（桁架高度）的关系，为拉索式预应力立体钢桁架结构方案的选取及设计提供了一定的参考依据。

| Abstract: | Based on the computational method established in this paper for optimization of the spatial cable prestressed steel trusses, different cable prestressed spatial steel strusses are analyzed. The relations expressed as a set of curves and tables between total steel products, the maximum deflection to span ratio and the pretension of the cables, external loads of the corresponding structures are obtained upon a large amount of computations. The effects of arrangement of cables and the height to span ratio on the optimum results are also studied. These results not only reflect some important properties of the special structures, but also provide some basis for plan choosing and design of the spatial cable prestressed steel trusses. |
