| 摘 要： | 通过70根层布式钢纤维混凝土小梁的弯曲疲劳试验,用双参数Weibull分布分析了其疲劳寿命,并进一步回归出不同失效概率下的单对数疲劳方程式,与国家现行纤维混凝土规范中的疲劳公式进行了衔接.试验结果表明:这种分层掺入少量钢纤维形成的混凝土,其抗弯疲劳性能较普通混凝土有大幅提高,且优于整体掺配钢纤维混凝土.

| Abstract: | Layered steel fiber reinforced concrete is a new type of composite material with perfect mechanical behaviors. Based on the fatigue tests of 70 small-scale beams, the fatigue lives were analyzed by the Weibull distribution method with two-parameter; and the fatigue functions were regressed for various non-survivorship probabilities. The fatigue behavior of the layered steel fiber reinforced concrete proves much better applications in engineering than the plain concrete and the steel fiber reinforced concrete. |
