Research on Calculation Method of Ultimate Bearing Capacity of Steel Structure Exposed Column Base

文中通过混凝土压弯构件的特性,分析了不同条件、不同工况下柱轴力的变化,并对柱脚极限承载力的影响分析,提出了更加准确安全的轴力选取方法,并针对适用外露式刚接柱脚的结构,给出了简化且安全的设计计算建议。

Based on the characteristics of concrete compression and bending members, this paper analyzes the changes of column axial force under different conditions and working conditions, and analyzes the impact on the ultimate bearing capacity of the column foot, and puts forward a more accurate and safe selection method of axial force. The simplified and safe design and calculation suggestions are given for the structure applicable to the exposed rigid column base.
