Integration of measured data for the seismic fragility assessment of deteriorated bridges

Abstract The reliable assessment of bridge capacity is necessary in order to ensure the functionality roadway network under normal, or emergency operating conditions. Damage due interaction with environment (e.g., corrosion coastal reinforcement) has been observed many cases, even newly built interurban road networks. Therefore, need for obtaining and including measured data fragility analysis emerged. In line above, proposed research introduces a framework bridges considering integrating obtained NDTs. scope NDTs track down evolution damage on determine its risk failure. work presents structural identification approach that successfully updates digital twin structure. Subsequently used fragility. Fiber modeling creating Modified uniaxial material laws are applied deteriorated case study also providing comparative results pristine bridge, i.e. without damage.
