Determine the epoxy modification factor, ψe, for a rectangular beam with b = 18 in. and d = 22 in., three epoxy-coated No. 9 Grade 60 tension-reinforcement bars placed in the top of the beam, and No. 3 Grade 60 stirrups located every 6 in. along the span. Assume 8,000-psi normal-weight concrete and a clear cover of 1.75 in.
