圆钢管混凝土短柱新模型轴心受压承载力计算

The calculation about the axial compression bearing capacity of the new model of the concrete short column with round steel pipe

通过对钢管混凝土短柱的重新设计使其外带钢筋混凝土结构层,既起到保护钢管作用又增强了其轴心受压承载能力,提出了轴心受压双混凝土结构计算模型,同时也通过对传统经典计算模型的研究,给出了混凝土和钢管协同工作计算模型的修正建议,此外,一些强有力的构造措施对实际工程实践也具有一定的参考意义。

Through the redesign of the steel pipe concrete short column to make its outer reinforced concrete structure layer,not only to protect the steel pipe and enhance its shaft pressure carrying capacity,put forward the axis pressured double concrete structure calculation model,but also through the study of the traditional classical calculation model,the concrete and steel pipe working together to calculate the model of the amendment proposal,in addition,some strong construction measures for the actual engineering practice also has a certain reference significance.
