In order to examine the fatigue strength of fatigue cracked flange gusset welded joints repaired by the bolting-stop-hole method, 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 have been carried out. On the basis of the results, the numerical expression for estimating the fatigue strength has been proposed.
