3. A rectangular beam having b = 10 in. and d= 17.5 in. spans 15 ft face to face of simple supports.
It is reinforced for flexure with three No. 9 bars that continue uninterrupted to the ends of the span.
It is to carry service dead load D = 1.27 kips/ft (including self-weight) and service live load L
3.70 kips/ft, both uniformly distributed along the span. Design the shear reinforcement, using No.
3 vertical U stirrups. The more approximate Eq. (5.12d) for Vê may be used. Material strengths are
f = 4000 psi and f₁ = 60,000 psi. Sketch your web reinforcement design for the half length of
beam. (10pt)
