Paper Title:
The Finite Element Analysis of Fatigue Performance of Precracked Concrete Beams Strengthened with Prestressed CFRP
  Abstract

The research conducts the numerical analysis of the fatigue performance of precracked concrete beams strengthened with prestressed CFRP, establishing the static analysis model (SM) and fatigue analysis model (FM) respectively, examining the change of the static loading and fatigue performance before and after CFRP strengthens precracked concrete beams in the different prestressed situations, and analyzing the relevant fatigue performance parameters through comparing FEM analysis with experimental results. The research results demonstrate that the method of strengthening concrete beams with prestressed CFRP can improve the static loading and fatigue performance; the increased rate of fatigue performance of precracked concrete beams is parallel to the CFRP prestress; the fatigue life of precracked concrete beams increases with the raising of the CFRP prestress; FEM analysis is in close agreement with experiment results; the fatigue properties of precracked concrete beams strengthened with prestressed CFRP can be analyzed effectively by the finite element method.
