Asap need right complete solution !!!
A prestressed concrete beam 221mm x 703mm has the following service loadings PDL=40 KN PLL=42 KN WDL=9 kN/m WLL=13 kN/m Loss of prestress at service loads is 18 % Throughout the span, the tendons are located 70 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.
