2. A concrete floor system consists of parallel T-beams spaced at 10-ft on centers and spanning 32-ft between supports. The 6 in thick slab is cast monolithically with T-beam webs having bw = 14 in and a total depth, measured from the top of the slab, of h= 28 in. The effective depth will be taken 3-in less than the total depth. In addition to its own weight, each T beam must carry a superimposed dead load of 50 psf and service live load of 225 psf. Steel yield strength 60 ksi and concrete strength of 4 ksi. Determine the required tensile steel area and select the reinforcement needed for a typical member.

Transcribed Image Text:2. A concrete floor system consists of parallel T-beams
spaced at 10-ft on centers and spanning 32-ft between
supports. The 6 in thick slab is cast monolithically
with T-beam webs having bw = 14 in and a total depth,
measured from the top of the slab, of h= 28 in. The
effective depth will be taken 3-in less than the total
depth. In addition to its own weight, each T beam must
carry a superimposed dead load of 50 psf and service
live load of 225 psf. Steel yield strength 60 ksi and
concrete strength of 4 ksi. Determine the required
tensile steel area and select the reinforcement needed
for a typical member.
