一、总论由于当前进一步要求好、省、快地建设,而某些结构材料又显得不足,因此经济地使用材料在发达的国家和发展中国家都不同程度地成了非常重要的问题之一。许多建筑师和工程师的经验表明,不仅在屋盖方面采用轻型空间结构是现实可能的,而且还可结合每个国家不同的技术和经济状况来处理。本文提供在某些国家所发展起来的著名的结构体系以及具有较好或较新处理方法的科研成果。列夫、柴得林在国际空间结构协会蒙特利尔《专家讨论小组》会上的发言“一个大型结构物首 I. General remarks As the current demand for better, provincial, and rapid construction, and certain structural materials are inadequate, economic use of materials has become one of the most important issues to varying degrees in both developed and developing countries. . The experience of many architects and engineers shows that it is realistically possible not only to adopt a lightweight space structure in the roof, but also to deal with the different technical and economic conditions of each country. This article presents the well-known structural systems that have been developed in certain countries and the scientific research results that have better or newer treatments.
