钢管混凝土结构在我国的应用和发展

摘要

Because of its higher load bearing, better plasticity and toughness, faster construction progress as well as its apparent economic profitability, technology of concrete filled steel tubular structure experienced a rapid development in engineering construction of China. A number of world level largest and highest buildings have been built in China. There are unique advantages and apparently comprehensive profitability for steel tube covered concrete used in high－ rise buildings and arch bridges. It must have desirable development prospective in the new millennium.%钢管混凝土具有承载力高、塑性和韧性好、经济效益显著和施工快捷等优点，因此在我国工程建设中发展迅速，已建成一些世界最大最高的工程。钢管混凝土用于高层建筑和拱桥有突出的优点，综合经济效益显著，在新千年中有很好的发展前景。
