摘要
同时考虑拉索刚度、钢索预拉力、边界弹性约束刚度及外荷载的随机性 ,得到了随机参数拉索预应力空间铰接钢结构随机内力摄动分析的一般公式及其统计特性的计算表达式 .文中所建立的计算模型为进一步进行拉索式预应力空间铰接钢结构的可靠性分析奠定了一定的理论基础 .
Considering the randomness of the cable stiffness, prestressed forces, stiffness of boundary elastic constraints and the applied loads, the general formula for random internal force analysis of prestressed spatial steel truss with random parameters and the formulation of statistical properties are presented. The computational models presented here form a theoretic foundation for further reliability analysis of the three-dimensional prestressed steel trusses. Finally, the computational examples are put forward for the triangular spatial steel trusses widely used in engineering.
