| 摘 要： | 研究了在相同的混凝土配合比情况下,对选用相同的钢纤维的层布式钢纤维混凝土和层布式混杂纤维混凝土的小梁进行弯曲疲劳试验,比较了两者各级应力水平下的平均疲劳寿命;并通过对试验结果进行统计分析,运用两参数威布尔分布拟合不同应力水平下两者的疲劳寿命,得出其特点和规律,回归出不同存活率的双对数疲劳方程.

| Abstract: | The flexural fatigue tests were carried out on both LSFRC and LHFRC beams of which the type of steel fiber was uniform on the same concrete mix in order to gain both fatigue life and compare both average fatigue life of different stress level.Then the data were analyzed in an attempt to simulate the fatigue life of their different stress levels through using the two-parameter Weibull distribution to obtain their fatigue characteristics and rule.And the double-logarithmic fatigue equations of different livabilities are regressed. |
