摘要：The hot pot stress (HSS) of a tubular joint is considerable because of the existence of stress concentration along the welding seam. To study the strategy for control stress concentration factor (SCF) of tubular joints, a typical five-planar tubular Y-joints as the connection between diagonal braces and the central column of a five-pile substructure is selected and simulated using FE method. Moreover, the corresponding reinforced FE models with three stiffened rings are established and calculated. The SCF distributions along weld seam, extreme SCF values, and sensitivity analysis of geometries parameters are performed and compared. ? 2019 by the International Society of Offshore and Polar Engineers (ISOPE).
