【摘要】 目前关于钢管混凝土轴压承载力的计算理论和方法很多,其中分别有针对实心或空心截面、圆形或方形及多边形的。按"统一理论"的思想,不论截面是实心或空心,圆形或多边形,它们的性质应该是统一且连续的,那么计算公式也应该是完全统一且连续的,而现有的计算方法多针对其中部分截面形式或有不连续的情况。基于此推论,本文在基于厚壁圆筒理论建立的圆形实空心钢管混凝土承载力统一计算公式的基础上,将其进一步扩展到多边形截面上,最终得到可以同时适用于实心和空心,圆形和多边形的轴压承载力统一计算公式。更多还原

【Abstract】 Based on the ideology of "Unified Theory",the capacity of members should be continuous and consistent whether the section is solid or hollow,circular or polygonal,then the formula to calculate the bearing capacity should be completely unified and continuous. But existing methods can only be used for some of the section types or the formulas are discontinuous. For this reason,based on the unified formula which is established on thick-walled cylindrical theory of circle concrete filled steel tube including solid and hollow section under axial load,the bearing capacity formula is expanded to the polygonal cross section. Finally,an unified axial bearing capacity formula is obtained,which can also be applied to solid and hollow,circular and polygonal section.更多还原
