A floor system uses 2×10 joists spanning 14 feet with a live load of 40 psf and dead load of 15 psf. If joists are spaced 16 inches on center, what is the total uniform load per joist?
Correct Answer
A) 73.3 plf
Tributary width = 16/12 = 1.33 feet. Total load = (40 + 15) psf × 1.33 feet = 73.3 plf.
Why This Is the Correct Answer
Tributary width = 16/12 = 1.33 feet. Total load = (40 + 15) psf × 1.33 feet = 73.3 plf.
