钢管混凝土结构是土木工程中常见的组合结构之一,尤其在高层建筑中应用十分广泛。本文以某超高层商业建筑的圆形钢管混凝土框架柱为研究对象,对比分析我国现行规范中钢管混凝土框架柱偏心受压承载力设计方法,并结合有限单元法分析各规程中钢管混凝土偏心受压承载力计算结果的区别,进而为工程实例的钢管混凝土框架柱的承载力设计提供参考。
The concrete-filled steel tube structure is one of the common composite structures in civil engineering, especially in high-rise buildings. In this paper, a circular CFST frame column of a super high-rise commercial building is taken as the research object. The design method of eccentric compressive bearing capacity of CFST columns in China is compared and analyzed. Combined with the finite element method, Bearing capacity calculation results of the difference, and then for the engineering example of the concrete-filled steel tube column bearing capacity to provide a reference.
