Abstract: Engineering calculation and estimation of the stress-strain state of the bearing elements of the superstructure is carried out. The analysis and collection of information on traffic intensity for 2019 was made. The history of loading a bridge structure with a real load is considered on the basis of a mathematical model (presented as a geometric progression) that shows the annual increase in traffic intensity along the bridge structure. The total fatigue damage of the bearing elements of the superstructure is determined according to the Palmgren-Miner hypothesis and the period of exhaustion of the operational resource of the bridge structure.

Keywords: load capacity, loading, history of loading, residual resource, the miner’s summation of fatigue durability.
