Limitation of equation for prediction the ultimate capacity of RC beams strengthened with CFRP in the case of premature failures

Abstract

In recent years, the method of external bonding of carbon fiber reinforced polymer (CFRP) is used for retrofing and strengthening of reinforced concrete beams. To determine the ultimate capacity of these beams we can't use classical method because of failure mode, nonlinear behavior of material and interface effect. For calculating load capacity, determination of premature failure mode is very important. In this paper we present a method to determine premature failure mode and ultimate capacity of RC beams strengthened with CFRP. Also we dispute about the limitations of applica -tion of proposed equation.
