Paper Abstract

This paper describes the results of a large-scale experimental test on T-tubular welded joint subjected under combined loading conditions. A special purpose rig is constructed for conducting the static and dynamic test of different tubular welded joints in the laboratory. The static test results are reported herein. Both the Strain gauge specimen testing which includes the basic brace axial, in-plane-bending, out-of-plane-bending and combined loadings cases, and also the finite element analyses had been carried out. The result obtained by the finite element analyses proved the accuracy and reliability of the numerical modeling. The study shows that the peak hot spot locations on the T-tubular joint subjected to combine loading shift from those of the basic load case. Generally, the peak hot spot stresses obtained by superposition are higher than that by direct analysis except for the areas that are near to the peak hot spot stresses location. The hot spot locations are important to decide on the placement of probes used in the fatigue test using the Alternating Current Potential Drop technique.
