Fatigue strength improvement of weld joints with cope hole
Abstract Weld joint with a cope hole has relatively low fatigue strength, since high stress concentration is generated due to local shear deformation inside the cope hole. In this study, fatigue strength improvement for the cope hole joint by burr grinding is investigated. I-section beams with cope holes, of which boxing weld toes were smoothly finished by burr grinding, were tested and analyzed in order to know the fatigue strength and the local stress behavior of the joint. Test and analysis results demonstrated that the benefit of grinding on fatigue strength improvement is relatively small when shear stress is largely applied to the cope hole detail.
