A3.2- The 4.5m long cantilever beam is subjected to the specified uniformly distributed dead load 7.0 kN/m
(including self-weight) and to the specified uniformly distributed live load 8.0 kN/m. The beam is made of
normal density concrete containing maximum 20mm aggregate size with f'c = 25 MPa. Design the shear
reinforcement for the beam using U-stirrups and fy = 400 MPa.
