摘要
提出了以影响结构概念为基础的拉索张拉过程的结构分析方法,建立了张拉过程 最优控制的数学模型,讨论了在各种施工条件下实现算法的途径.所提出的方法能够 在满足所有中间状态的机具能力、内力和位移约束条件下,达到预先给定的设计状 态,解决了大型柔性组合结构施工中的一个困难问题.
A structural analysis approach considering the variation of the structure system during cable-stretching has been presented by means of the concept of the influence pattern and used to formulate a general model for the optimal control of a cable-stretching process. In various cases of construction solution of the model has been investigated. The model enables the structure to reach the design state and to satisfy all constraints such as stretching equipment capability, stress and displacement in all middle states.
