【 摘 要 】

The paper is focused on the comparison of Wöhler’s curves for concrete in accordance with fib Model Code 2010 and EN 1992-2. It discusses the great difference for bridge fatigue assessment between Model Code 2010 and EN 1992 observed in previous studies. Respective S-N curves were compared with the experimental data for concrete C20. Evaluation is performed for concrete exposed to compression only. Wöhler’s curve in fib Model Code 2010 is more complex and can better fit experimental data than the Eurocode model.
