| Title of the article | Estimation of road bridges resource indicators based on the analysis of structural changes and damage accumulation in structural elements |
| Abstract. | Problem statement. The purpose of the study is to develop a generalized algorithm for analyzing the structural state of bridge structures structural elements, which allows, by selecting control and controlled factors, to assess the resource indicators of bridge structures. Results. The main results of the study consist in the analysis of the values of the conditional probability of failures at characteristic points of the operating time (at the time of the assessment, to the depth until the next scheduled inspection and to the depth to the expected exhaustion of the project resource), which characterize the reserves of the carrying capacity of the system under the conditions of static strength and fatigue strength (durability). Conclusions. The significance of the results obtained for the road bridges design consists in improving and optimizing the procedures for calculating the road bridges steel structures for strength and endurance. |
