Calculation of Stress-Strain State of Overpasses
https://doi.org/10.30932/1992-3252-2019-17-1-58-69
Abstract
The article considers the results of the design analysis of supporting structures of overpasses with a single-track railway line. The obtained stress-strain states in the elements of reinforced concrete span structures and intermediate supports under given loads using spatial finite-element models allow us to compare them with the normalized load range and the level of real stability and reliability of bridge objects. In this case, the need arises to monitor such states to maintain viability of the structures in use.
