Statistical Analysis for Fatigue Life of Concrete
Statistical analysis is presented for 108 groups of fatigue test data of concrete, including tests of abnormal value, variance and distribution-fitted with fuzzy optimization; analysis of variance, sample size and error. It is chiefly concluded that effect of stress level of repeated loading on the fatigue life of concrete is much more significant than that of stress rate and relative stress amplitude, and effect of stress rate and relative stress amplitude are of the same significance; Relationship of sample size, relative error and significant level is also presented; fatigue life of concrete is more fitted for lognormal distribution than Weibull distribution. Suggestion for relevant code, standard and regulation are presented.
