Research on Deflection of Strengthening Concrete Beam with Prestressed CFRP Sheets
CFRP sheets have been widely used in strengthening concrete structures as a new material and prestressed CFRP sheets can improve the carrying capacity of beams. This paper researched the affection about the deflection and rigidity of concrete structures after strengthening with prestressed CFRP sheets, and derived related theoretic formulas. It is shown that the prestressed CFRP sheets can not dramatically change the deflection of the structures because the prestressed CFRP sheets are generally thin with small moment of inertia for the structural sections.
