索穹顶结构施工控制反分析

索穹顶结构是本世纪八十年代美国工程师 Geiger运用 Fuller的张拉整体概念而开发的一种实用大跨空间结构体系，与传统结构分析不同的是索穹顶的成形分析是个关键。本文针对上述问题，提出了施工控制反分析法，从而确定各个阶段的理想施工状态参数 (包括索力和标高 )，此时结构不仅满足自平衡要求，且按此状态施工，可以达到理想的设计形态。这一方法力学概念清晰，计算简便，通过对一些典型索穹顶结构的施工控制模拟计算，证明其结果符合实际工程要求。

Inverse Analysis of Construction Process of Cable Dome

Cable dome is a new style of space structure developed by Geiger on the basis of Fuller's tensegrity theory.Unlike the traditional method,the analysis of construction process of this structure is the key problem.A new method of inverse analysis is provided in this paper to give out the parameters of ideal status in each step of construction,including internal forces and the coordinates of points.Program has been developed and two numerical examples are given in detail.The results show that this method is clear in conception and convenient in calculation.It can be used in engineering practice very well and can meet the needs of engineering.
