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 Keywords: prestressed。 theoretic formulas。 2 1 Introduction Carbon fiber reinforced plastic (CFRP) sheets which are characteristic of high strength, light weight and anticorrosion are widely adopted in strengthening, but the capacity of high strength in CFRP can39。 the reinforced bar have already been under some tensile strain and the concrete in the tensile area may have already had cracks. The deflection of the structures in usage should be calculated separately. Taking Btype prestressed concrete member as a reference, according to Reference [3], 3 the bending rigidity is calculated segment by segment according to the moment of the bination for shortterm action effects under the action of cracking moment cr M ： B0= I0 （ ?） under the act
