Abstract: Taking a reinforced concrete frame structure as an example,in order to reduce the influence of the original rectangular reinforced concrete column on the indoor usable floor area and decoration,the equivalent box shaped concrete-filled steel tubular special-shaped column was used to replace its rectangular reinforced concrete column.The mechanical properties of CFST special-shaped columns are analyzed based on the mechanical properties of the frame structure.The result shows that the equivalent box shaped CFST special-shaped column can meet the design requirements of small earthquake elasticity,and can effectively reduce the column section and increase the indoor use area.

Key words: frame structure, concrete filled steel tubular columns, optimal design

摘要: 文中以某钢筋混凝土框架结构为例,为了减少原有矩形钢筋混凝土立柱对室内使用面积和装饰的影响,采用等效箱型钢管混凝土异形柱替换原有矩形钢筋混凝土柱,结合框架结构立柱受力对钢管混凝土异形柱力学性能进行分析,结果表明:采用的等效箱型钢管混凝土异形柱满足结构小震弹性的设计要求,能够有效减小立柱截面,增加室内使用面积。
