张拉整体结构的预应力优化设计

OPTIMUM DESIGN OF PRESTRESS FOR TENSEGRITY STRUCTURES

张拉整体结构是一种新型的空间结构体系，其设计理论至今尚未完善，其中的预应力设计问题也是一样。本文应用线性规划理论，提出了多自应力模态张拉整体结构预应力优化设计的方法。该方法比现有文献的方法有了很大的改善。本文应用所提出的理论与方法，编制了计算机程序，并进行了算例分析。算例计算结果与文献［１］的模型试验结果基本吻合。文中还指出了进一步完善张拉整体结构优化设计的途径。

Abstract Tensegrity structure is one kind of new space structure systems. However, its design theories still need to be improved. This paper presents a method of prestress optimum design for multi selfstress mode by means of linear programming theories. The method has many advantages in comparision with those given in the current references. The corresponding computer program is developed and an example is calculated in this paper. The results of calculation are basically compatible with those gotten by model test. The paper also gives an other approach for improving optimum design of tensegrity structures.
