The effect of internal ring stiffeners has been studied theoretically and experimentally for the welded tubular T-joints occurring in conventional jacket type offshore structures. Four welded tubular joint models of T shape, with different diameter ratios have been tested under axial loading in the branch. The analytical results have been obtained by finite element technique. The results indicate a significant reduction in the stress concentation factor and a fairly uniform transfer of load from branch to the chord. A simplified analysis of stiffener rings have been proposed. The stress results of joints strengthened by ring stiffeners and joint can are compared.
