Dead Load Calculations:

Typical Bay Size:
30’x30’

Maximum Tributary Area per floor per Column:
30’x30’=900 sq. ft. x 3 floors=2,700 sq. ft.

Typical column size:
W10x45
Weight per typical bay:
(45 lbs./ln.ft.)(16 ln.ft.)= .72 k/bay

W-section girder size:
(30’x12)/16=22.5= W24x94
Weight per typical bay:
(94 lbs./ln.ft.)(60 ln.ft.)= 5.64 k/bay

K-series joist size (spacing 4’ on center):
(30’x12)/20=18= 18k6
Weight per typical bay:
(8.5 lbs./ln.ft.)(30 ln.ft.)(8 joists)= 2.04 k/bay

Deck Slab (for floor plates) size:
4”
Weight per typical bay:
(900 sq. ft.)(4/12)(0.150)= 45 k/bay

Total Dead Loads per typical bay:
53.4 k/bay
