A prestressed concrete beam 410mm x 572mm has the following service loadings PDL-55 KN PLL-84 KN *Concentrated load acts on the midspan WDL=12 kN wDL=11 kN. Loss of prestress at service loads is 18 % Throughout the span, the tendons are located 69 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. PDL, PLL. WDL, WLL 16m A T B
