摘要：
Results of an investigation conducted to estimate the flexural fatigue strength of Self-Compacting Concrete (SCC) made with Coarse Recycled Concrete Aggregates (RCA) are presented. The statistics of the fatigue data have been analyzed by employing Weibull distribution and the fatigue data has been further used to determine the experimental constants of the fatigue models based on S-N relationships, which can be adopted to estimate the fatigue strength of SCC mix containing Natural Aggregates (NA) or RCA. A probabilistic approach has been adopted to estimate the fatigue strength by developing S-N-P-f relationships for SCC mixes under consideration. The experimental constants of the fatigue models based on S-N-P-f relationships have also been determined to estimate the fatigue strength of SCC mix containing NA or RCA. The graphical representation of S-N-P-f relationships has been presented in the form of S-N-P-f curves for estimation of fatigue strength for desirable failure probability.
