Design a 20-inch wide reinforced concrete rectangular beam having a simple span length of 32 ft, Wp=2 k/ft (not including beam weight), WL=1.8 k/ft and p=1/2 pb , using the following: 1- Assume beam weight=640 Ib/ft; 2- Round up the value of “d" to the nearest 0.5 inches, and use h=d+2.5; 3- Use #10 for beam reinforcement; fy=60,000 psi, f'c=4000 psi; 4- Assume concrete weight=150 lb/ft3 Show sketch of beam cross section and dimensions, including bar sizes, arrangement, and spacing. Be neat.

Transcribed Image Text:Design a 14-ft simply supported reinforced concrete slab to carry a uniform dead load (excluding
self-weight) of 110 psf and a uniform live load of 90 psf, using the following:
1- f'c=4 ksi, fy%360 ksi, and the ACI Code limitations;
2- #4 bars for the Main steel, and #3 bars for the Temperature and Shrinkage steel;
3- Rebar cover%3D3/4"
Provide a detailed sketch of the slab showing its thickness, span, Main steel, and Temperature
and Shrinkage steel with their spacings.
