BEHAVIOR ANALYSIS AND CRACK INITIATION PREDICTION OF TUBULAR T-CONNECTIONS

A program system based on the finite-element method was developed for the detailed behavior analysis of the vicinity of intersection of tubular T-connections. This program system consists of a nonlinear shell analysis program, a nodal data generation program, and a nonlinear solid analysis program. The strain distributions calculated by this program system show a good agreement with experimental results. Experimental results of fatigue crack initiation life of tubular T-connections are evaluated by applying the calculated equivalent strain amplitude into the fatigue strength curve for the same material as that of the connections and into the X-curve in AWS Code, suggesting unsatisfactory safety factor to the X-curve, especially in the lower cycle range.
