Determine the dead load on the beam A, where each (wood) beam is 4 inch × 16 inch in cross-section and is spaced 6 ft on the center. The (wood) floor planks are 2.5 inch thick. Assume that the density of wood is 40 lb/ft3

Solution

density of wood=40 lb/ft³

cross section of each beam = 4inx16in

self weight of beam = (4/12)*(16/12)*40=17.78 lb/ft

Thickness of wood planj=2.5\"

self weight of plank = (2.5/12)*40=8.33 lb/ft²

spacing of beams=6 ft

dead load of plank=8.33*6=50 lb/ft

Total dead load = 17.78+50=67.78 lb/ft
