本文给出了受拉荷载作用下Ｔ型管节点静承载力的实用计算方法──等效单环 法。该方法通过对带弹簧圆环的极限承载能力的计算来模拟Ｔ型管节点的受力全过程，简 单适用，能根据不同变形要求得出管节点的静承载力。本文对已有的试验结果进行了 计算比较．结果比较吻合。
This paper presents a practical calculation method for the static bearing capacity of T-tube joints under tensile load—the equivalent single ring method. This method simulates the whole process of the T-type pipe joint by calculating the ultimate bearing capacity of the spring-loaded ring, which is simple and applicable, and can obtain the static bearing capacity of the pipe joint according to different deformation requirements. This paper compares the existing experimental results. The results are more consistent.
