An Study on the Flexural Performance of Reninforced Concrete Beams Considering Loading History with Pre-Stressed Cfrp Sheets

Abstract:

For the effect of nonpre-stressed carbon fiber reinforced polymer (CFRP) Sheet Strengthening concrete beams to improve bending stiffness and crack resistance is not satisfactory, and it is difficult to totally unloading on the actual reinforcement, so in this paper, ANSYS is used to research the strengthened effectiveness and impact factors of pre-stressed CFRP reinforced concrete beams considering the secondary load.
