STATISTICAL DISTRIBUTION OF AXLE-LOADS AND STRESSES IN RAILWAY BRIDGES. MOMENT RANGE SPECTRA IN RAILWAY BRIDGES, DERIVED FROM THE STATISTICAL TRAFFIC SPECTRUM

The report gives a statistical representation (statistical traffic spectrum) of railway traffic considered as a succession of vehicles (axle loads, axle spacings and order of succession of axles). It outlines the method for deducing from this the statistical distribution of the static bending moment ranges at the middle of a bridge of arbitrary span (moment range spectrum). The calculations are fairly short and the method lends itself well to the analysis of the influence of different traffic parameters.
