摘要
在室内混凝土试件弯曲疲劳试验的基础上,研究了素混凝土受弯试件在等幅重复荷载作用下的弯曲疲劳性能。通过对试验结果的统计分析,证实了混凝土弯曲疲劳寿命的概率分布基本上符合两参数威布尔分布。在探讨了疲劳方程合理形式的基础上,进而建立能够较好拟合试验结果。
This paper studied the fatigue properties of the plain concrete under constant amplitude flexural cyclic loading.The flexural fatigue tests were carried out on concrete specimens and the data were analyzed in an attempt to develop the relationship for concrete between the stress level S and the number of cycles to failure N .It is found that the probability distribution of N is in good agreement with the two parameter Weibull distribution,and this relationship can be expressed in a traverse linear log log form.
