Strength of Welded Pipe-plate Joints (original) (raw)

The distribution of stresses of the welded pipe-plate joints is complicated. To study the strength of the joints, the parameter analyses were undertaken using nonlinear finite element method and uniform design approach. The pipe diameter, thickness, the plate width, height, and thickness were considered. Three kinds of loading conditions on the plate-the axial force, the moment, the combined axial force and moment were analyzed. The strength formulas of the joints are proposed by regression analysis. The verification tests demonstrate the reliability of the formulas.
