中文摘要：
阐述了空间结构的发展历史，根据各个时期空间结构的发展特点、形式类型和科技水平可区分为古代空间结构、近代空间结构和现代空间结构，说明了促进空间结构发展创新的因素．文中提出并论述了刚性空间结构、柔性空间结构和刚柔性组合空间结构三大类空间结构的组成及其分类方法．文中将国内外现有工程应用的38种形式的空间结构按单元组成来分类，并说明采用空间结构按单元组成分类总图来表示是可取的、清晰明了的．
英文摘要：
This paper describes the development history of spatial structures and classifies spatial structures into ancient spatial structures, modern spatial structures and contemporary spatial structures according to the development characteristic, types of form and the state of science and technology of spatial structures in all periods, points out factors that boost the development of spatial structures. The composing and classification of rigid spatial structures, flexible spatial structures and rigid-flexible combined spatial structures are presented and discussed. 38 types of spatial structures which have been applied in practical engineering are classified based on element composing, and the classification figure of spatial structures on the basis of element composing is clear and suitable.
