In this report a simplified design method of bolted joints against fatigue is described and it is discussed from a practical viewpoint. Two type of bolted joints are treated; one is the simplest cylindrical joint, and the other is more practical T-flange joint. The relation between the load applied to the above mentioned joints and the stress in the bolts are calculated by using spring-beam model. A diagram is proposed in which the fatigue limit (Haigh) diagram is superposed on the relation between the appied load and the axial stress in the bolt of the joint. The fatigue failure of the bolt can be estimated by comparing the stress in the bolt to the fatigue strength of the bolt in the above diagram. The estimated values of fatigue strength show good agreement with the experimental results which have been published.
