railway bridge, girder superstructure, stress-strain stateAbstract
This article presents some results of instrumental measurements of the stress-strain state of a reinforced concrete girder superstructure of a railway bridge under operational loads during the passage of various mobile loads. The results obtained can be used in further monitoring of similar structures on the main lines of JSC NC KTZ and in the preparation of algorithms for detecting damage in bridge structures.
