Select the lightest available A992 Wsection for beam AB in the ﬂoor system shown below using AISC
LRFD provisions. The conventional reinforced concrete ﬂoor slab is 6 inches thick. The selfweight of the
beam must be taken into account. The uniform live load is 110 psf. There are no other loads. The maximum
allowable deﬂection is L/240. Assume that the ﬂoor slab provides continuous lateral bracing for the beams.
