RELIABILITY ANALYSIS OF CONCRETE FATIGUE LIFE UNDER SPECTRUN LOAD BASED ON RESIDUAL STRENGTH DEGRADATION
-
-
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 spectrumloading. The experiments show that the present method is reliable, theanalysis and calculation is simple and effective.
