Practical Computing Method for Bearing Capacity of Tubular T-Joints

This paper presents a computing method for static bearing capacity of tubular T-joints under tensile loading. This method is a complex approach combining finite element method of shells and displacement method of framed structures. It is applicable to engineering design and can be used to determine not only the load-deformation curve but also the static bearing capacity of a real tubular joint. In this paper, the computed results are compared with those of empirical formulas by other researchers. Our computed results are varified by experimental results with good agreement, Finally, the criterion of static bearing capacity of tubular joints for engineering has been discussed and the deformation is proposed to be the controlling factor for failure of tubular joints,
