For the I section prestressed concrete beam with a straight tendon shown in Fig
below which is under the prestressing force, and U.D.L. Analyze the stresses at Mid-
span at: A- transfer stage (due to initial prestress P. and self weight wo)
B- at service stage. (due to effective prestress Pe and full loads)
Check stresses with the ACI permissible stresses.
Given:
Initial prestress force Pi = 750 kN
Effective prestress force Pe = 640 kN
