An engineering method of predicting fatigue life of projected metallic span structures of railroad bridges made of modern high-strength materials is proposed. An analytical solution of the problem takes into account the unsteady process of loading of span structures by rolling loads, as well as the results of a generalization of the data of fatigue tests of structural elements from a probabilistic-statistical point of view. The method is illustrated by examples. It is shown that, in comparing the technical and economic efficacy of metallic span structures, their costs of construction are of decisive importance.
