| 摘 要： | 为了更合理地模拟实际边界条件，本文在钢桁架各支承处引入一组弹性约束，并以边界性约束刚度的随机性，在建立拉索式预应力钢桁架基本计算基本理论的基础上，推导了拉索式预应力钢桁架随机内力摄动分析一一般公式，并给出了算例。

| Abstract: | A group of elastic constraints are used at each support of a steel truss to simulate the practical boundary conditions properly, Considering the randomness of the stiffness of the boundary elastic constraints, the general formulas in the analysis of the random internal forces of the prestressed steel truss are presented in this paper, it being the use of the method of perturbation. In the paper, numerical examples are given. |
