if the given beam section is used for a simply supported beam 6.5 m span, using f'c=21MPa and fy=280MPa. 1. Calculate the ultimate shear strength of concrete (kN) using simplified formula of NCSP 2015. 2. calculate the nominal shear strength of the stirrups, Vs, in kN. 3. calculate the design sectional shear strength of the beam in kN.

A continuous concrete beam shown in the figure has a width of b= 300 mm, an effective depth of d= 560 mm, and an overall depth of h= 600 mm. Concrete compressive strength fIc=21.0 MPa and steel yield strength fy= 275 MPa. The beam carries a superimposed dead load at span AB of 7.5 kN/m and at span BC, CD of 4.5 kN/m. A live load at span AB of 12.5 kN /m and at span BC, CD of 10.5 kN/m. Determine the number, N, of 20 mm ∅ deformed steel bars at the following sections1) support A 2) Support B 3) Support C4) between AB 5) between BC
