STUDIES OF STRESS CONCENTRATIONS AND TOLERANCES FOR WELD DEFECTS IN FULL-SCALE TUBULAR JOINTS

Tests were conducted on full-scale tubular joints (1) to investigate the effects of joint scale and steel strength on the stress concentration and ultimate failure characteristics of the joints and (2) to evaluate weld defect tolerances for the prevention of brittle fracture. Simple T and cross joints made of mild steel and high strength steel were used for the test models and subjected to static compressive and tensile loads through the braces. In the second step crack opening displacement (COD) tests were performed on small specimens taken from the welded joints of the cross type models. A method of applying fracture mechanics technique to material selection and fabrication is presented, and its reliability is discussed.
