A prestressed concrete beam 326mm x 875mm has the following service loadings PDL=64 KN PLL=86 kN wDL=8 kN/m WLL=18 kN/m Loss of prestress at service loads is 17 % Throughout the span, the tendons are located 71 mm below the N.A.. If the allowable compressive stress is 15.75 MPa and the allowable tensile stress is 2.96 MPa, and considering the point of maximum moment, calculate the required Prestressing force in KN.
