摘要
综述了钢管混凝土结构理论研究及应用的现状和新进展.对钢管混凝土的静力性能,长期荷载作用下的力学性能、动力性能及耐火性能等研究成果做了概述,并对其粘结性能研究、钢管高强高性能混凝土研究、火灾后剩余承载力研究等最新研究进展和关键技术进行了介绍.总结了钢管混凝土结构在拱桥和高层超高层建筑中的应用,并对其需要进一步深入研究的关键技术问题进行了探讨.
The current situation and new progression of theoretical investigation and application of concrete filled steel tubular (CFST) are summarized briefly. The investigation results of static performance of steel tubular concrete and its mechanical, dynamic, and fireproof properties under longtime action of the load are also related generally and the adhesion of that concrete is investigated also. New progression of the investigation such as that of highstrength and highperformance steel tubular concrete and its postfire residual bearing capacity is introduced together with the key techniques for them. Finally, the application of steel tubular concrete structure to the construction of arch bridges and tall buildings is briefly summarized and the key technical problems need to be further investigated are discussed.
