摘　　要：CT型 (Compression- Tensegrity)索结构 (简称 CT结构 )是在研究了张拉整体(Tensegrity)结构 (简称 T结构 )优缺点的基础上开发的一种新型索结构。它保留了 T结构的优点 ,结构效率高于 T结构 ,材料用量低于 T结构 ,节点构造易实现 ,施工方法简单 ,屋面系统选型范围宽 ,造价较低。此结构属线性时不变系统 ,力学分析和结构设计较方便 。The CT type cable structure is developed as a new type of cable structure based on the research of advantages and shortcomings of tensegrity structures. It is composed of tensile cables and compression elements which obtained by substituting compression elements for those unloading cables under loading duration after computation of the tensegrity system. This type of structures keeps the advantages of tensegrity structure and has more advantages and more efficiency than tensegrity structures. At the same time, it saves more construction materials and has more economial benefits. So it can be widely used. [
