Comparison and calibration of numerical models from monitoring data of a reinforced concrete highway bridge

Resumo

The last four decades were important for the Brazilian highway system. Financial investments were made so it could expand and many structural solutions for bridges and viaducts were developed. In parallel, there was a significant raise of pathologies in these structures, due to lack of maintenance procedures. Thus, this paper main purpose is to create a short-term monitoring plan in order to check the structural behavior of a curved highway concrete bridge in current use. A bridge was chosen as a case study. A hierarchy of six numerical models will be shown, so it can validate the bridge’s structural behaviour. The acquired data from the monitoring will be compared with the finest models so a calibration can be made.
