Select an A992 W-shape for beam AB of the floor system shown in Figure. In addition to the weight of the beam, the dead load consists of a 5-inch-thick reinforced concrete slab (normal-weight concrete). The live load is 80 psf, and there is a 20-psf partition load. The total deflection must not exceed L/240.
a. Use LRFD.
b. Use ASD
Select an A992 W shape for beam AB of the floor system shown in Figure. In addition to the
weight of the beam, the dead load consists of a 41⁄2-inch-thick reinforced concrete slab (normal-weight concrete). The live load is 95 psf. The total deflection must not exceed L/240.
a. Use LRFD.b. Use ASD..
Part 1
The simply supported beam below is initially designed to undertake a concentrated factored live
load of 45 kips (215 kN). Assume that the beam is laterally supported and the self weight
neglected. Use: A992 steel (Fy= 50 ksi or 345 MPa) E = 29 x 10® psi (200 GPa), the maximum
allowable deflection Aall = L/360
45 kips

1/ Determine the most economical W shape beam required
Part 2
The most economical selected beam from Part 1 ends up being subjected to a concentrated live
load of 20 kip.
Determine the corresponding maximum live load deflection.
Part 3
Assuming that the beam will only be braced laterally at the supports and every quarter spam
points (8ft from each support), verify whether the chosen cross section still checks under the live
load of 20 kips only. If not, what are your design recommendations?
