张弦结构的十年(一)——张弦结构的概念及平面张弦结构的发展

DEVELOPMENT OF CABLE-SUPPORTED STRUCTURES IN THE LAST TEN YEARS(1)——CONCEPT OF CABLE-SUPPORTED STRUCTURES AND DEVELOPMENT OF PLANE CABLE-SUPPORTED STRUCTURES

自第一个将张弦梁用于大跨度屋盖的工程——上海浦东国际机场(一期工程)航站楼竣工以来,此类结构在我国得到迅速发展。收集到的1998—2008年间关于此类结构的理论分析、试验研究和工程实践的论文有近300篇,工程应用已有近70项,很值得回顾与梳理。通过对此类结构的组成和受力特点的讨论,建议将此类结构统称为张弦结构,其中又可分为单向、双向、空间张弦结构和张弦成形结构。最后介绍单向张弦结构的工程应用和最新的研究进展,讨论需进一步关注的问题。

Since the completion of terminal building of Shanghai Pudong International Airport （phase- I ）, where the first cable-supported structure was used, the cable-supported structures （CSS） have been developed rapidly. There are about 300 papers on analyzing, test and application of CSS and about 70 projects from 1998 to 2008. In this paper the concept of CSS, including one-way CSS,two-way CSS,spacial CSS and cable-supported forming structures, was discussed. The development of one-way CSS in the last ten years was introduced. Some problems needing attention were also presented.
