A rectangular beam having b=300 mm and d=575 mm, spans 5.5 m
face to face of simple
supports. It is reinforced for flexure with 4φ32 bars that continue
uninterrupted to the ends of
the span. It is to carry a service dead load wD=30 kN/m (including
self-weight) and a service live
load =45 kN/m both uniformly distributed along the span. Design the
shear reinforcement using
φ10 vertical U stirrups. Use the equation (a) for Vc. Material
strengths are fc’=22 and fy=420 MPa
