摘　　要：介绍了一种自应力自平衡的张力单元结构,这种单元结构由5杆8索构成,文中证明了它的几何稳定性,分析了结构性能与几何外形参数之间的关系,进而构造了一种由此类单元组合而成的平板网架。A self - stressed equilibrium unit structure made of five struts and eight cables is introduced. Analysis proves that it is stable and could be gathered up in to assembled grids, the relatives between geometrical parameters and its structural behaviors are also studied.

关 键 词：张拉整体 索杆结构 单元 几何参数
