| 摘 要： | 采用三分点加载研究了不同应力水平下钢纤维砼梁试件的疲劳寿命及其分布规律，这些分布规律是不相同的。，采用图解法，矩方法，极大似然估计法得到的ＳＦＲＣ疲劳寿命布尔分布诸参数颇相一致。

| Abstract: | The steel fiber reinforced concrete (SFRC) beam specimens are tested under three point flexural loading. Fatigue life distributions of SFRC for various levels of applied stresses are investigated. The test results indicate that the distributions of fatigue life of SFRC are different for different stress levels. The graphical method, method of moments, and maximum likelihood estimation yield very similar values of distribution parameters. |
