STATISTICAL DISTRIBUTION OF AXLE-LOADS AND STRESSES IN RAILWAY BRIDGES. RANDOM LOADING OF RAILWAY BRIDGES AND ITS RELATIONSHIP TO FATIGUE

Random models of railway bridge loading are used to study its accumulative fatigue damage. The effect on the bridge life of different parameters such as speed, damping, traffic load, number of stress ranges and their distribution, etc., is studied. The report also includes the development of an experimental method to obtain bridge stresses under traffic loads. The derived method of designing railway bridges for fatigue allows for the traffic load, the probability of trains passing one another on bridges carrying several tracks, Wohler curves and the life for which a bridge is designed.
