A simply supported beam (B-2) supports a uniformly distributed load and is braced at six foot intervals (see Figure 8.48) in addition to a composite slab that is secured to the compression flange of the beam via shear studs. Assume that the beam is made of ASTM A992 grade with F_{ y } = 50 ksi.
Select the lightest W shape to safely support the following loads:
DL = 100 psf; LL = 75 psf
Beams are spaced at 12 feet o.c.
