Sažetak
When assessing an existing bridge, the application of conservative design load and resistance models can cause unnecessarily high maintenance costs. On the other hand, sophisticated methods based on probabilistic approach require greater effort and are also demanding for practical application. Consequently, multi-level assessment procedures are considered appropriate, whereby complexity and accuracy increase consecutively through the levels. Namely, if the bridge meets the requirements at the first assessment level - on the safe side, no further complicated steps are needed. Otherwise, a more complex assessment step should be carried out in which we are closer to the real values of the structure's performance and resistance. In this paper, (i) the multi-level assessment of road bridges for traffic load and (ii) the multi-level seismic assessment of arch bridges, will be overviewed. In addition, recommendations for further development of assessment procedures will be provided, based on undergoing research. The first research branch explores the value of implementing the Bridge-Weigh-in-Motion measurements together with the probabilistic approach in assessment of existing road bridges. The second research branch aims to reveal seismic resistance of bridge elements with nonstandard sections and smooth reinforcement designed without contemporary rules for ductile behaviour.
