Evaluation of Damage in Steel Bridges with Different Dimensions under Loading

In contemporary practice, many existing steel bridges can be evaluated in terms of their structural integrity and potential vulnerabilities. Researchers employ such evaluations to assess bridge performance, estimate damage-prone regions, and predict service life. Accordingly, these assessments are often conducted using probabilistic approaches and through specialized technical investigations, either in laboratory settings or within computational environments. For this purpose, two probabilistic scenarios were applied to three bridges of different dimensions. In one case, damage assessment was carried out by eliminating certain structural elements. The analyses were performed using the ABAQUS software, and the results demonstrate that various loading scenarios lead to distinct structural responses and differing damage conditions. Furthermore, in another investigation, three predefined failure modes were imposed on the bridge model within the first scenario to enable the prediction of potential damage levels.
