THE IMPACT OF BRIDGE CROSSING SPAN DAMAGE UNDER MOVING LOAD

DOI: 10.17804/2410-9908.2023.2.065-074

The structure of the bridge crossing span structure is simulated in order to determine the most informative parameters, which need to be measured in the process of monitoring system operation. To assess the influence of structural component integrity on the static deflections and dynamic response, damages were introduced into the model, which were simulated by removal of a part of the structural components. On the basis of a numerical model of calculating a span structure under static and dynamic moving load, it is shown how increasing damage changes deflection and natural frequencies, which can be reliably recorded by the monitoring system.

Acknowledgments: The work was performed under the state assignment to the Perm Federal Research center, UB RAS, theme No. AAAA-A19-19012290100-8.

Keywords: damage, span, numerical calculation, monitoring system, moving load
