STRESS ANALYSIS OF RING STIFFENED TUBULAR JOINTS FOR OFFSHORE STRUCTURES——REVIEW OF STUDIES IN CHINA

摘要

In China, the stress analysis of tubular joints for offshore structures was started at the end of 1970’s . In addition to simple joints, the ring stiffened tubular joint have been analyzed recently. In this paper, the author reviews the research work of stress analysis of ring stiffened joints, including brief introduction to the methods used, stress concentration behaviour, effects of ring stiffeners’ number, location, dimension, type and stress distribution of ring stiffeners. Emperical formulae for predicting SCF of ring stiffened joints are also presented.
