摘　　要：文中以苏州IFS超高层项目巨柱为例,对SRC巨柱的轴压比、压弯承载力、抗剪承载力、剪跨比及巨柱在分析中的模拟方法进行了研究,结果表明巨柱截面大小主要取决于结构的整体刚度的要求、初始偏心距对巨柱承载力影响巨大,得到了苏州IFS结构中巨柱基本均可视为长柱的结论;对巨柱箍筋设置及巨柱的模拟方法给出了建议。Based on the project of IFS of Suzhou, this paper studies the design method of the mega column in axial compression ratio, bending bearing capacity, shear bearing capacity and shear span ratio, etc. The results show that the section of the mega column mainly depends on the requirements of the overall stiffness of the structure and the initial eccentricity has a great impact on the bearing capacity of the mega column. The mega columns in Suzhou IFS structure can be considered as long columns. Some suggestions have been given on the column stirrup and the simulation method of the mega column.
