Abstract

A theoretical model for predicting the strength of ring-stiffened tubular T-joints in offshore structures M. M. K. Lee, BSc, PhD, CEng, MICE, MIStructE, and A. Llewelyn-Parry, BEng Although not commonly used in modern design, ring stiffeners were extensively used to enhance the strength of tubular joints in older offshore steel jacket structures. No detailed guidance on the determination of the strength of ring-stiffened joints can be found in any major offshore code. There is therefore a need for research for the purposes of structural assessment when platforms are upgraded or modified...
