| Abstract: |
This article presents the results of a study of long-term degradation processes: corrosion of steel structures and rebar, metal fatigue, loss of pre-stress, which reduce the load capacity and durability of bearing bridge structures. In addition, the parameters of the probability distribution according to the normal law of the impact on the bridge elements of loads from heavy vehicles, as well as the forecast of the growth of road live loads over time are obtained. The algorithm for determining the residual life of the durability (pre-repair terms) of bridges is compiled on the basis of probabilistic criteria of limit States. |
