Determine the casting-position modification factor, ψt, for a rectangular beam with b = 16 in. and d = 23 in., five uncoated No. 9 Grade 60 tension-reinforcement bars placed in the bottom of the beam, and No. 3 Grade 60 stirrups located every 8 in. along the span. Assume 5,000-psi lightweight concrete and a clear cover of 2 in.
