摘　　要：提出了单元拼装式自平衡预应力空间结构的概念,阐述了此种结构形式的受力机理及特点,以一个28m跨的空间网架结构为例,介绍了基本单元、材料、截面形式及节点的设计,并对结构施加预应力阶段和使用荷载作用阶段的内力、变形进行了仿真分析。The concept of spatial grid assembled with self- balanced pre - stressed elements was presented.The mechanism and performances of this kind of structure were represented. The designs of basic elements, section types and joints were introduced by a 28m span spatial grid example. Internal forces and deformations in pre- stressing and loading phases were simulativeUy analyzed.
