In order to study the influence of steel tube diameter thickness ratio on the bearing capacity of steel tube angle steel tower joint, the finite element model of tube plate joint was established, and the failure mode and bearing capacity of the joint under different steel tube diameter thickness ratios were studied, and the influence law of steel tube diameter thickness ratio on the bearing capacity of steel tube tower joint was obtained, and the relationship between steel tube diameter thickness ratio and steel tube tower joint bearing capacity was established through regression analysis in this paper. The results show that angel steel tube plate K-type joint has two kinds of failure mode, and in a certain range, the bearing capacity of the joints increases with the increase of the steel tube diameter thickness ratio, and decreases after reaching the maximum bearing capacity.

为研究钢管径厚比对钢管角钢塔接头承载力的影响，建立了管板接头有限元模型，研究了不同钢管直径下接头的失效模式和承载力。对厚度比进行了研究，得出了钢管直径厚度比对钢管塔接头承载力的影响规律，并通过回归分析建立了钢管直径厚度比与钢管塔接头承载力的关系。纸。结果表明，天使钢管板K型接头有两种失效模式，在一定范围内，接头的承载能力随着钢管径厚比的增加而增加，
