[摘要]20世紀90年代前,空間結構主要采用薄殼、網(wǎng)架、網(wǎng)殼、懸索等結構形式。為了滿足設計的基本需要,結構分析集中采用連續(xù)化理論的解析法和離散理論的線性有限元分析法。在隨后的20多年里,面對空間結構應用的大好前景和發(fā)展需求,結構體系在創(chuàng)新中百花齊放,結構分析方法也發(fā)生了質的飛躍。值空間結構分會20年慶誕之際,從網(wǎng)殼穩(wěn)定性分析、新型柔性結構分析、風致響應分析、地震響應分析、精細化模型分析、施工全過程仿真分析等方面梳理了空間結構分析技術發(fā)展的脈絡,以期為空間結構分析技術的再續(xù)輝煌盡綿薄之力。

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
