STATISTICAL DISTRIBUTION OF AXLE LOADS AND STRESSES IN RAILWAY BRIDGES. BENDING MOMENT SPECTRA AND PREDICTED LIVES OF RAILWAY BRIDGES

The report presents bending moment spectra at mid-span points for simple beams and predicted lives of railway bridges for 10 spans from 2 to 50 m. The bridges are subjected to various typical trains of 7 European railway administrations, the trains run at different speeds. For the fatigue life of bridges, the moment histories are analysed by the rainflow counting method and Palmgren-Miner cumulative damage theory is used.
