Determine the transverse reinforcement index, Ktr, for a rectangular beam with b = 17 in. and d = 24 in., three uncoated No. 8 Grade 60 tension-reinforcement bars placed in the bottom of the beam, and No. 3 Grade 40 stirrups located every 6 in. along the span. Assume 4,000-psi normal-weight concrete and a clear cover of 1.75 in.
