Conduct service level flexural design based on the midspan section. This member is to be

designed as a class U member. Use the PCI load table in Fig. $3$ to choose a preliminary section

geometry. Assume the maximum practical tendon eccentricity is at $3$ in$.$ from the bottom of the

section. Construct the feasible domain to select the least number of strands needed and

corresponding tendon eccentricity. If the tensile stress at prestress transfer exceeds the

allowable limit$,$ mild steel reinforcement may be added to compensate the tensile stresses,

however, all other allowable stress limits must be met. $(20$ pts$)$
