Abstract In this paper, a methodology is developed to investigate the combined effect of some main factors (bolt pretension load, shear coefficient friction, and bolted joints structure) on fatigue performance joints. A parameter k, which reflects ratio bolt load used evaluate competition fretting stress concentration damage The analysis result deduces that as increase decreased, while influence increased. At crack formation position will be far away from hole center. This k can design or assembly improve strength
