| 中文摘要: |
| 本文在建立拉索式预应力钢桁架基本计算理论的基础上，考虑到拉索刚度的随机性，推导了拉索式平面预应力钢桁架随机内力摄动分析的一般公式及敏度分析式，并给出了算例。为进一步进行预应力钢桁架可靠性分析奠定了基础。 |
| 英文摘要: |
| On the basis of establishing the fundamental computational theory of the cable prestressed steel trusses, the general formulationes of the random internal force analysis and sensitivity analysis of the plane prestressed steel trusses are presented in consideration of randomness of the cable stiffness based on the perturbation methods, and also some computational examples are put forward. The results can be used as the basis of reliability analysis of the prestressed steel trusses. |
