N2  - The paper deals with experimental and theoretical investigations in reinforced concrete structures strengthened with carbon fiber sheets. Four stages in the behavior of concrete structures strengthened with the carbon fiber reinforced polymer (CFRP) are distinguished. A method for calculating the deflections of such structures is presented. The design procedure for defining the strength of structures evaluates the stiffness of the contact between the carbon fiber and the concrete. Experimental investigations with different fastening methods of the CFRP to the concrete were performed. In experimental investigations, deflections of the strengthened members were examined. Results of the calculations of deflections for experimental beams according to the proposed method are presented. A comparison of experimental and theoretical deflections is presented in the paper.<p />
