| 摘要： | A novel model based on the three-parameter Weibull function is proposed to describe the three-stage fatigue deformation behavior of plain and fiber-reinforced concrete. The fatigue strain at a particular stress between zero and the maximum fatigue stress can be modeled using the proposed model, and all the model parameters have clear physical meanings. This model is validated via comparison of its results with previously reported results of compressive, tensile, and flexural fatigue tests. Cases of application of the model to plain concrete and fiber-reinforced concrete with high ductility are examined in order to investigate the variation of the model parameters. Additionally, a deformation-based method for prediction of the fatigue life of concrete is presented, and the prediction results demonstrate that the proposed model can be successfully applied to the estimation of the fatigue life of concrete materials. |
