) A 1200 mm deep by 750 mm wide post-tensionedsimply supported beam is shown below. The beam spans 12.0 m and issubject to a superimposed dead load of 50 kN/m and a live load of35 kN/m. Both the superimposed dead load and live load are appliedafter transfer (after stressing has taken place). The tendon islocated at the mid-height of the beam at each end, and itscentreline sits 50 mm from the base at midspan. The concretestrength at transfer is 22 MPa, and at maturity is 40 MPa. AssumeE_c = 32800 MPa,Î³_c = 24 kN/m³ andignore any prestress losses.
q= If P_i = 1750 kN and allthe load has been applied, determine the percentage of the totaldead load balanced
