Determine the epоxy mоdificаtiоn fаctor, ψe, for а rectangular beam with b = 17 in. and d = 21 in., five uncoated No. 8 Grade 60 tension-reinforcement bars placed in the bottom of the beam, and No. 4 Grade 40 stirrups located every 6 in. along the span. Assume 5,000-psi normal-weight concrete and a clear cover of 2 in.
