Question

The interior floor system shown in Figure 2.2 has W sections spaced 8 ft on
center and is supporting a floor dead load of 50 psf and a live floor load of 80 psf. Determine the governing load in lb/ft that each beam must support.

D = 55 lb/ft + (8 ft)(50 psf) = 455 lb/ft
L = (8 ft)(80 psf) = 640 lb/ft
