| 摘 要： | 介绍一种适合于评价低弹性模量纤维混凝土弯曲特性的剩余弯曲强度概念，并对聚丙烯纤维混凝土垢剩余弯曲强度进行了试验研究，与弯曲韧性指数相比，低弹性量纤维混凝土的剩余弯曲强度不仅可以更好地评价纤维混凝土弯曲开裂后的强度和韧性，而且可用来简化配筋纤维混土正截面强度计算，具有显著的力学意义。

| Abstract: | It is introduced to the concept of post-peak strength for evaluating the flexural characteristics of low elastic-modulus fiber reinforced concrete. Based on experiments of polypropylene fiber reinforced concrete, it has been found that post-peak flexural strength had an important mechanical significance. It can be used not only to evaluate the strength and toughness properties after flexural cracking, but also to simplify the calculation for normal section flexural capacity of low elastic modulus fiber reinforecd concrete beam. |
