DEFLECTION OF REINFORCED CONCRETE BEAMS STRENGTHENED WITH FIBER-REINFORCED POLYMER (FRP) PLATES

This paper investigates the deflection of reinforced concrete beams strengthened with fiber-reinforced polymer (FRP) plates. The calculated deflections of reinforced concrete beams strengthened with FRP using Branson's equation, adopted by the American Concrete Institute Code, were found to be underestimated. Therefore, a method for calculating the deflections of FRP-strengthened reinforced concrete beams is proposed. In addition, alternative expressions for calculating the effective moment of inertia for FRP-strengthened beams at the cracking and postcracking stages are developed. The deflections calculated using the proposed expressions were found to correlate well with the measured deflections in laboratory beam tests. A numerical example illustrating use of the proposed procedure is appended.
