One-Way Slab Design
Need to confirm thickness is adequate for one-way
shear. Difficult to place shear reinforcement in
a slab.
Minimum area of shear reinforcement required in
slabs if
ACI Sec. 11.5.51
Usual use

One-Way Slab Example
The cross section of a continuous one-way solid
slab in a building is shown. The slabs are
supported by beams that span 24 ft. Between
simple supports. The dead load on the slabs is
that due to self-weight plus 60 psf The live
load is 120 psf. Design the continuous slab and
draw a detailed section. Given fc 3 ksi, fy
40 ksi.
