拉索预应力空间网格结构的计算分析方法

Analysis method of pretensioned reticulated structures

本文将拉索预应力空间网格结构中预应力的本质归纳为拉索的初始缺陷，并从初始缺陷的角度出发，提出了拉索预应力空间网格结构的一般计算分析方法．特别对该结构施工阶段分批张拉时的力学问题，提出了一种简便的计算方法．文中的算例验证了以上方法的正确性和有效性．

In this paper,the prestress in the pretesioned reticulated structure is owed to the lack of fit in the tendons.A general analysis method of this structure is discussed.Specially,some mechanics problems in the construction of this structure analyzed in detail.In the end,a examples is analyzed and proved that the method above is right and effective.
