摘 要: 针对钢管混凝土(concrete-filled steel tubular, CFT)柱在建筑等领域日趋得到广泛应用的现状,对国内外现行主流设计规范推荐的关于轴压和偏压钢管混凝土柱承载力的计算方法进行比较,并利用国际钢-混凝土组合结构协会(Association for Steel-Concrete Composite Structures, ASCCS)数据库提供的钢管混凝土组合柱试验数据对各种规范推荐的钢管混凝土柱承载力的设计方法进行对比分析。通过试验数据与理论计算值的比较,给出了各设计规范精度和离散性。
关 键 词: 结构工程;钢管混凝土柱;承载力;现行规范

Abstract: Application of concrete-filled steel tubular (CFT) columns becomes more and more popular in building and construction engineering. This article presents a comparative study of main current design methods of different countries for the load-carrying capacity of concrete-filled steel tubular columns, and the differences between the current design methods in assessing the load carrying capacities of the composite columns the under axial loading and the eccentric loading are commented. Comparison analysis is carried out on the test data from the (Association for Steel-Concrete Composite Structures, ASCCS) database against the calculated results derived from the main current design methods for the composite columns, and the accuracy and discreteness of the methods are analyzed.
Key words: structural engineering; concrete-filled steel tubular column; ultimate capacities; main codes
