Originální abstrakt

Presented here is an assessment of the limit state conditions of a prestressed bridge beam with its prestressing steel affected by corrosion. The proposed approach is based on probabilistic methods and simulation techniques, taking into account the uncertainties of the relevant variables while modelling hydrogen induced stress-corrosion cracking (SCC). The software package FReET-D for the stochastic assessment of degradation effects in reinforced concrete structures is utilized for SCC modelling and service life assessment. The deterministic model is based on the fracture mechanics approach. As an illustrative example, a precast prestressed bridge girder damaged by SCC is presented.
