张拉整体结构是由不连续的受压构件和连续的受拉绳索组成的特殊结构体系.由于其轻质,非连续,容易形成大跨度等特征,张拉整体结构从上世纪60年代提出后就成为国际研究热点.本文主要叙述了张拉整体结构过去50年来的发展历程.传统张拉整体结构通常是索杆结构,早期的研究集中在张拉整体结构理论与力学分析上.由于经典张拉整体结构的自由度大,结构具有随机性,不易于控制,从上世纪80年代末开始,人们不再拘泥于经典张拉整体结构整体的构造,转而探索新的控制性与运用性强的包含张拉整体结构原理的模型,特别是大跨度的模型,同时对预应力的研究也有了很大发展.进入21世纪以后,除了对索杆张拉整体结构的研究,含有空间三维受压构件的张拉整体模型成为新的研究方向,计算机模拟对张拉整体模型的布局控制和构件的找形也有了进一步的发展.
Tensegrity is an assemblage of ension and compression components arrange d in a discontinuous oyable modular interested since in the last fifty years. Early researches were focused on the form-finding and mechanism of classical cable-strut tensegrity structure. Since 1980' s, it is not limited to the pure tensegrity structure and some more controllable structures which contain stretch-draw concept, especially long span structures is developed. Coming to the new century, tensegrity structure contains 3D compressed components becomes a new tendency in tensegrity research, computer aided form-finding and assembling technology are also rapidly developed.
