The assessment of technical condition of bridge and recommendations for strengthening the load-bearing structures

Abstract

The article evaluates the technical condition of an existing road bridge and proposes methods for strengthening its load-bearing structures. It presents the results of diagnostics, calculations for accommodating standard temporary loads (A11, NK-80, A14, NK-100), and provides recommendations for increasing the bridge's load-bearing capacity. To distribute the temporary load between the slabs of the span structure, the method of eccentric compression was employed. A reinforcement technique is proposed, involving the installation of a new reinforced concrete layer on the existing bridge deck to extend the bridge's service life and ensure traffic safety.
