Analysis on the ultimate bearing capacity and stability coefficient of lightweight aggregate concrete filled steel tubular long columns under axial compression
According to the theoretical analysis and the experimental data, it concludes that the lightweight aggregate concrete filled steel tubular concrete have the same intensity as the ordinary and even much higher, which results it can be well used in the large span structure. This article calculates the stability coefficient of the medium long column with different slenderness ration through the theoretical calculation and the experimental data, and uses the least squares method of numerical analysis to fit the quadratic curves of the supporting capacity and stability coefficient of the medium long column with different slenderness ration. At last, discovering the stability coefficient will decrease: at the same slenderness ration, the bigger steel ration is, the smaller stability coefficient of the medium long column will be. In addition, the columns stability coefficient with higher rate of steel decrease slower as the slenderness ratio increases.
