| Abstract: | The mechanical behavior of carbon fiber reinforced concrete dominantly depends on its load history. Through parametric study and experimental investigation, the model of stress-strain and the formula of residual plastic deformation under repeated load are proposed. The presented model is initiated to provide flexibility mathematical expressions which can be changed according to the materials properties. |

| Keywords: | carbon fiber reinforced concrete repeated loading stress-strain relationship |
