摘要
为了解决混凝土结构疲劳分析过程中混凝土材料S-N曲线选择问题,根据国内外混凝土材料疲劳试验资料,建立适用于疲劳分析的混凝土材料S-N曲线模型,结合试验数据与既有相关模型的精度进行比较,研究结果表明所建立的模型精度较高,为疲劳数值模拟提供参考。
In order to select optimal S-N curve of concrete materials during the fatigue analysis of concrete structures, the model of S-N curve of concrete for fatigue analysis is established, based on the fatigue test data at home and abroad. Then the newly established model is compared with the existing related models on accuracy, as a result, the accuracy of the model is higher, which provides reference for the numerical simulation of fatigue.
