层布式钢纤维混凝土疲劳寿命的概率分布拟合

Probability Distributing of Layer Steel Fiber Reinforced Concrete Fatigue Life

通过疲劳试验得到上下层布式钢纤维混凝土的疲劳寿命 ,采用对数正态分布、两参数威布尔分布分别对疲劳寿命进行概率分布拟合 ,经比较得出两参数威布尔分布能更好地拟合上下层布式钢纤维混凝土的疲劳寿命 ;

By fatigue test, this paper gets fatigue life of LSFRC and further simulates fatigue life with probability distributing by Gauss method and Weibull method, respectively. And it is found that the Weibull method is better for the simulation. Moreover, the fatigue equations of LSFRC by Gauss and Weibull methods are concluded in this paper.
