Study of the Technical Condition of the Bridge Structure

The assessment of bridge structures is not only relevant, but also an integral part of effective infrastructure management aimed at ensuring safety, convenience and comfort for citizens. Many bridges have been destroyed due to imperfect design, the use of low-quality materials, and inappropriate construction methods. Consideration of natural and human factors in the design, construction and operation of bridge structures is key to ensuring their safety, durability and long-term performance. Any defects require careful monitoring, assessment and timely repair to ensure the safety and reliability of bridges. Various methods are used to inspect bridge structures. Inspection methods can be used individually or in combination to obtain comprehensive information on the condition of bridge structures and take the necessary measures for their maintenance and repair. In work to determine the stresses in a bridge, we use the finite element method (LIRA 9.4 R3). The inspection of the bridge's structures revealed a number of defects resulting from corrosion processes, operational factors and certain structural deficiencies. To ensure the durability of the bridge structures, it is necessary to reconstruct the bridge.
