三棱台张拉整体塔结构研究

介绍了张拉整体塔结构的工程概况、张拉整体的基本概念以及模块化设计思想，并阐述了建筑设计和结构设计的情况。分析对比了作为张拉整体模块体中受压构件的斜索螺旋柱、水平索螺旋柱、铰接水平系杆中心柱和固接水平系杆中心柱等四种索柱的形式，论述了模块张拉设计和结构安装设计等施工设计，最后介绍了试验模型的制作情况。

Study on Tensegrity Tower Composed of Truncated Triangular Pyramid

Based on the concept of tensegrity system, the concept of modular design and the module of the truncated triangular pyramid are proposed. According to the actual engineering requests and the concept of modular design, model analysis and design of the tensegrity tower composed of the truncated triangular pyramid are carried out in the following aspects: form, components, boundary conditions, prestress and load values. Then the model manufacture of the tensegrity tower composed of the truncated triangular pyramid is completed. Two kinds of different levels of prestress are introduced into the tensegrity model, and the most disadvantageous direction of horizontal static loads is found out, and then structural characteristics, such as the stress-load curve and the displacement-load curve, are obtained.
