摘　　要：对我国钢管高强混凝土结构技术的发展现状作了简要介绍。着重评述了在高层建筑、大跨度桥梁工程中应用钢管高强混凝土结构的成就。工程实践表明,钢管高强混凝土既是一种高强、高性能结构材料,也是一种高效施工技术。The state of the art of the steel tube confined high strength concrete(STCC) structures in recent decade in China is introduced in this report. The general situation in utilization of STCC in tall buildings(up to 72 stories)in earthquake areas, long span arch bridges(up to 420m in span) and cable stayed bridge is emphatically described. The beam column connection, construction method and economy of STCC are also discussed. The engineering practice shows that STCC is not only a high strength and high performance structural material, but also a high efficient construction technique. The technology of STCC in combination with techniques of high strength and pumped concrete would yield a deep influence upon the future development of civil engineering.
