Bolting-Stop-Hole Method i s one of useful repair methods for the fatigue crack in welded steel structures. The authors have already proposed empirical formula for estimating the fatigue strength of steel members repaired by this method under axial stress or in-plane bending stress field. In this study, for the purpose of evaluating repair effects of the method against web gusset welded joints with fatigue cracks under combined stress field (normal stress and shear stress) and indicating an expression formula for evaluation on the fatigue strength of the repaired joints, finite element stress analyses and fatigue tests have been performed on model specimens.
