Bayesian estimation of characteristic S-N curves for reinforcement bars and proposal for the national annex of NEN-EN1992-1-1

report
The focus of this report is on the assessment of the characteristic (5% fractile) S-N curves for reinforcement bars, based on fatigue tests performed at constant stress amplitude [1] which have been performed in The Netherlands in the past years. Five datasets of experimental tests are considered in the investigation. The diameter of the bars varies between 12 and 25 mm and it includes straightened and welded bars. The characteristic S-N curves have been derived by using a probabilistic fatigue model already available in literature [2] and a statistical technique for the characterization of the model parameters from the available experimental data.
