STIFFNESS AND YIELD STRENGTH OF SIMPLE V-JOINT OF OFFSHORE STRUCTURE

A simple (unstiffened) V-joint of an offshore structure was investigated, being a three-dimensional joint, of which two braces exist in a plane perpendicular to the axis of the chord. The mechanical behaviour under various loads was analysed using the plastic node method. The results showed the stiffness and strength of the V-joint in comparison with those of a T-joint of the same dimensions. The elastic-plastic behaviour is dependent on the loading condition, and the mechanism of the influence upon the stiffness and strength was clarified. One of the most important results from the study was that the stiffness and strength of the V- joint is reduced to 70% of that of the T-joint in a severe loading condition. Reinforcing using a stiffener is discussed.
