A rectangular beam having b=16 in and d=26 in spans 28 ft face
to face of simple supports. It is reinforced for flexure with 6#11
bars that continue uninterrupted to the ends of the span. It is to
carry service dead load 2.0 kips/ft (including self weight) and
service live load 3.6 kips/ft, both uniformly distributed along the
span. Design the shear reinforcement using vertical U stirrups.
Economize the spacing of stirrups in appropriate number of bands.

2. A rectangular beam with b = 12 in., d = 17 in., and h = 20 in. spans 23 feet from simple supports. Each support is 12 inches wide (clear span between face of supports = 22 feet). The unfactored dead load (excluding self-weight) = 0.9 k/ft, and the unfactored live load = 1.25 k/ft. As = 6.0 in.2 . Material strengths are f’c = 3,500, fy = 60,000 psi. Shear reinforcement consists of #3 stirrups at 8 in....

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 (No. 29) 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 (No. 10) vertical U stirrups. The more approximate...

m 3: (20 points) Design the stirrup spacing for the beam shown below. Change your design between Zones 1, 2, and 3 of the beam length, using a uniform spacing in each zone. Ignore the self-weight of the beam. Loads on the beam are service loads so load factors must be applied according to ACI 318 (subscripts "d" and T" denote dead and live loads, respectively). Material strengths are fe 4,0oo psi and fy 60,000 psi. The total factored shear...
