Assuming that the internal tension steel yields and the concrete fails in compression prior to the FRP strip failing or detaching, the nominal moment capacity, M n, of the MF-FRP strengthened RC beam can be determined from (6) M n = A s f y d s-a 2 + A frp f f d frp-a 2 where, A s is the area of the steel tensile reinforcement, f y, is the ...
