［摘要］20世纪90年代前，空间结构主要采用薄壳、网架、网壳、悬索等结构形式。为了满足设计的基本需要，结构分析集中采用连续化理论的解析法和离散理论的线性有限元分析法。在随后的20多年里，面对空间结构应用的大好前景和发展需求，结构体系在创新中百花齐放，结构分析方法也发生了质的飞跃。值空间结构分会20年庆诞之际，从网壳稳定性分析、新型柔性结构分析、风致响应分析、地震响应分析、精细化模型分析、施工全过程仿真分析等方面梳理了空间结构分析技术发展的脉络，以期为空间结构分析技术的再续辉煌尽绵薄之力。

Abstract:

Before the 1990s, spatial structures mainly adopt the forms such as thin-shells, grids, latticed shells and suspen-cable structures. The analysis methods based on continuous theory and the linear finite element analysis methods based on dispersed theory were used universally in designing of spatial structures. Following development of spatial structures and innovation of the structural system, structural analysis methods have also been expanded by leaps and bounds during 20 years passed. For the 20 anniversary of Association for Spatial Structures, the development and application of analysis methods of spatial structures about stability of latticed shells, new flexible structures, wind-induced response, earthquake response, meticulous model and simulation of construction process were presented to card the development process,which provides brilliant contribution for analysis technologies of spatial structures.

Keywords: spatial structure; thin shell structure; grid structure; latticed shell structure; suspended-cable structure
