大跨空间结构的发展——回顾与展望

DEVELOPMENT OF LONG-SPAN STRUCTURES--A REVIEW AND PROSPECT

大跨空间结构是目前发展最快的结构类型.大跨度建筑及作为其核心的空间结构技术的发展状况是代表一个国家建筑科技水平的重要标志之一.本文就空间网格结构和张力结构两大类介绍了国内外(但主要是国内)空间结构的发展现状和前景.对这一领域几个重要理论问题,包括空间结构的形态分析理论、大跨柔性屋盖的动力风效应、网壳结构的稳定性和抗震性能等问题的研究提出了看法.

The spatial structures have been developing most rapidly in recent years. The state of the development of long-span buildings together with the innovative spatial structures being used are usually considered as one of the important symbols representing the level of development of construction science and technology of a nation. A review and prospect of the development of spatial structures in the world, but mainly in China, has been made in this article for spatial latticed systems and for tensile systems, respectively. Some key theoretical problems related to the development of spatial structures, such as the shape analysis of spatial structures, dynamic response analysis under wind action for flexible (cable and membrane) structures, seismic response and stability problem of lattice shells and etc., have been discussed.
