Theoretical foundations for calculating bridges for endurance using the kinetic theory of durability of structural materials

Abstract


The economically effective method for determining the unknown parameters of the dependence of the durability of structural materials on the level of acting constant stresses in them and their absolute temperature for various structural materials is proposed, taking into account the data established by Academician of the USSR Academy of Sciences S.N. Zhurkov. It does not require long-term testing of materials, but is based on the use of the results of short-term standard machine failure of two groups of standard samples of materials at two significantly different temperatures. When using these parameters and the Bailey integral criterion for summing up the losses in the durability of materials, it is possible to calculate the endurance of elements of road bridge structures from any structural materials and to determine the residual durability resource of the structure under the predicted subsequent mode of loading it with real temporary vertical loads.
