| 摘 要： | 本文以高应力循环比为变参数，通过试验研究了先高后低两级变幅载荷作用下钢纤维混凝土轴向压缩疲劳行为．结果表明：当高应力循环次数低于某临界值时，高－低两级应力下的疲劳累积损伤和将大于１．０．

| Abstract: | An experimental stUdy on axial comressive fatigue action of stal fibre reinforced conerete under high-low two level variable-amplitude loading is intiduced in this paper. The cyclic ratio of high stress level is a variable parameter. It is shown that if the cyclic ratio of high stress level is less than the critica value, then the fatigue cumulative damag sum will be greater than 1.0. |
