| 摘 要： | 目的研究素混凝土和纤维混凝土疲劳性能．方法通过纤维体积率等不同参数比较了素混凝土和纤维混凝土的疲劳性能．结果素混凝土不存在疲劳极限；纤维混凝土是否存在确定的疲劳极限值仍属未知；钢纤维提高混凝土疲劳性能在受弯作用下比受压要好很多．结论尽管关于混凝土疲劳特性的说法并不统一甚至矛盾，但多数研究认为纤维的存在有益于改善混凝土的疲劳特性．

| Abstract: | The general overview of recent developments in the study of fatigue behavior of plain and fibre reinforced concrete(FRC) is reported in this paper.The fatigue performance of plain concrete and FRC is compared in order to investigate the influence of parameters such as fiber volume on fatigue behavior.It is proved that plain concrete does not have a fatigue limit while for FRC it is uncertain.Fiber addition benefits the fatigue performance under flexural loading more than it does under compressive loading.Despite the contradicting information obtained so far,it is accepted that the existence of fiber can enhance the fatigue life of concrete. |
