Abstract: Based on the concrete $S$-$N$ curve, a model of residual strength degradation is established in this paper, and then both the fatigue life and its reliability are modeled and analyzed by using this degradation model and the three-parameter Weibull distribution under spectrum loading. The experiments show that the present method is reliable, the analysis and calculation is simple and effective.

Key words: S-N curve, fatigue life, residual strength, spectrum load
