摘要
本文通过试验研究了钢纤维混凝土承受轴向等幅循环压应力时的疲劳破坏特征,分析了疲劳寿命的分布规律,给出了不同存活率下钢纤维混凝土的S—N曲线方程.
The experimental study on the fatigue failure characteristics of SFRC subjected to constant amplitude axial compressive cyclic stress is presented in this paper. The distribution law of fatigue-life of SFRC is analyzed, and the S-N curve equation of SFRC under different probabilities of survival is given.
