Abstract

This study aims at examining the fatigue strength of fatigue cracked out-of-plane gusset welded joints repaired by the stop-hole or the bolting-stop-hole method. For this purpose, following examinations have been performed. They are fatigue tests on as-welded joints and the joints repaired by the stop-hole or the bolting-stop-hole method, stress measuring tests and stress analyses using three-dimensional finite element method in consideration of plate thickness, hole diameter and crack length. On the basis of the results, the evaluation formula for the fatigue strength has been proposed, and validity of the formula is verified by comparing the predicted results with the experimental ones.
