Question

- The concrete slab of size 40 foot by 36 foot by 5-inch-thick is reinforced with #4 rebar at 16 inches on center both ways. The rebar is lapped 18 inches. Determine the number of 20-foot-long bars of #4 rebar needed to reinforce the slab.

Answer #1

You are working on a mix design and have been asked by the
engineer to recommend the maximum size aggregate that can be used
in the mix. The concrete is for a continuously reinforced concrete
slab. The slab is 10 inches thick and will be reinforced with No. 6
bars (3/4-inch diameter) at 6 inch on-center (so a 5 1⁄4 inch space
between the bars). The bars will be placed just above mid-depth of
the slab so they have 4...

A fully grouted reinforced concrete masonry wall, composed of 8
inch (7.63 in. effective) thick hollow concrete masonry units laid
out in full bedding is reinforced with #6 (Ab = 0.44 in2 ) Grade 60
bars (fy = 60,000 psi) at 25 inches on center. Find the wall load
capacity for pure compression and pure flexure conditions. The
compressive strength of the masonry, f’m, is 2000 psi.
