| 中文摘要: |
| 基于文（１）所建立的拉索式予应力钢桁架基本计算，根据矩阵摄动原理进一步给出了以竖向为位移为约束反演确定任意布索张拉予应力钢桁架单元刚度和的索刚度的摄动迭代公式。算例表明，该方法具有较高的精度，可满足工程设计需要。 |
| 英文摘要: |
| Based on the fundamental theory of computation of the cable\|prestressed steel trusses established in paper[1],the iterative perturbation formulas which inversively determine the stiffenesses of elements of steel trusses and cables with the restraint of vertical displacements of the truss are put forward on matrix perturbation principle. Some computational examples show that the methods presented here has higher accuracy, and can meet the need of engineering design. |
