| 摘 要： | 根据修订钢纤维混凝土结构设计与施工规程的需要,对钢纤维混凝土的抗折疲劳强度进行了研究.在分析钢纤维对钢纤维混凝土疲劳特性提高机理的基础上,提出钢纤维混凝土抗折的基本疲劳方程,以及在常用应力比范围内与现行水泥混凝土路面设计规范相衔接的设计疲劳方程.对比计算表明,新设计疲劳方程与现行钢纤维混凝土规程的设计疲劳方程计算结果非常接近,可供修订钢纤维混凝土技术规程时参考.

| Abstract: | An attempt is made to revise the current code of steel?fiber?reinforced?concrete(SFRC) structures. A general equation describing the fatigue performance of SFRC in a large stress range is proposed in the paper,which is in accordance with that of the current pavement design code. It is validated by the available flexural fatigue test data and the enhanced mechanism of SFRC. Comparisons between the results of the proposed equation and those computed according to current SFRC specification have shown that the two equations are equivalent in the stress range of pavement in practice. |
