大跨度建筑及与之相应的大跨空间结构的发展程度是反映一个国家建筑科学技术水平的重要标志之一。近二十年来,我国在平板网架方面发展很快。但在悬索结构、网壳结构、薄壳结构和薄膜结构等其它空间结构型式方面,进展则较为缓慢。与国外相比,差距较大。这种相对落后状态在近年来迅速发展的体育馆建设中已被明显地感觉出来。在考虑这些大跨度建筑的设计方案时,深感选择余地不多,受结构选型的限制较大,不能适应对于建筑物的多 The degree of development of large-span buildings and their corresponding long-span spatial structures is one of the important signs reflecting the level of science and technology in a country’s architecture. In the past two decades, China has developed rapidly in flat-screen grids. However, progress has been slower in other types of space structures such as cable-stayed structures, reticulated shell structures, thin-shell structures, and thin-film structures. Compared with foreign countries, the gap is greater. This relatively backward state has been clearly felt in the construction of stadiums that have been rapidly developed in recent years. When considering the design of these large-span buildings, there is not much room for choice and there is a limit to the selection of structures that cannot accommodate many buildings.
