Coupled damage in assessing the lifetime of bridges and viaducts

Exceptional and cyclic external actions on structures affect the structural performance of bridg- es. As the prediction of the remaining life for all deteriorated structures is a key issue to maintain a safe net- work, the development of assessment models to evaluate structural changes in these structures are needed. Fa- tigue, seismic, and other concurring minor damages as corrosion need to be investigated in coupled manner. In this paper, damage causing cracking or even failure is analyzed together with different scenarios of propaga- tion. Prediction of the remaining life for a real structure is illustrated.
