The frame shown in Figure 1 supports a 6 in. concrete slab, a superimposed dead load of 40 psf, and a live load of 80 psf. The concrete has a f'c = 4000 psi and reinforced steel strength fy = 60,000 psi. Design the slab reinforcement using a maximum positive moment of wl²/11 for the end span between gridlines 1 and 2 and # 3 bars. Include the temperature and shrinkage reinforcement.

The frame shown in Figure 1 supports a 6 in. concrete slab, a superimposed dead
load of 40 psf, and a live load of 80 psf. The concrete has a f'c = 4000 psi and
reinforced steel strength fy = 60,000 psi. Design the slab reinforcement using a
maximum positive moment of wl²/11 for the end span between gridlines 1 and 2 and
# 3 bars. Include the temperature and shrinkage reinforcement. Perform all necessary
checks, list all assumptions, and include the final sketches.
