A section of a prestressed concrete beam 150 mm x 300 mm carries a factored shear force of 110 kN and a factored bending moment of 25 kNm. The prestressing steel index is 0.4, and the effective prestress after all losses is 600 MPa. Compressive stress at centroidal axis due to prestress is 6.5 N/mm. Design suitable shear reinforcement. Assume ock 35 21 N/mm, Op = 1600 N/mm", Ap= 150 mm and cover to reinforcement is 60 mm.
