摘要
以两种不同的等效方法ＲＭＳ和ＲＭＰ计算等效载荷，并用这两种等效载荷研究渐增块载条件下的疲劳寿命，经数值计算表明ＲＭＳ和ＲＭＰ方法的结果是比较接近的，而且也较好地符合了实验结果。
This paper discussed the fatigue life of structures loaded by gradually increasing block loading.The calculated fatigue life with two kind of equivalent loading methods,RMS and RMP,and quite close and basically correspondent with the experiment results.It is suggested that the two equivalent loading methods could be used to calculate the fatigue life of structures loaded with variable amplitude loading in defect assessment.
