Abstract
A procedure was developed of plotting design S-N curves for the main types of welded joints for in-service structures, using a specially developed software for PC. Obtained design S-N curves of welded joints were compared with the results of fatigue testing of large-scale specimens.
Keywords: welded joint, bounded fatigue limit, stress concentration factor, S-N curve, software, residual life
