Below is a screen shot of a spread sheet I created for calculating live loads according to my building's program and the loads per sq. ft. found in //Table 3.1// in __B__//__uilding Construction__.//


 * __LIVE LOADS:__**




 * __DEAD LOADS:__**

//__LOOKING at CIRCULAR THEATRE SPACE ONLY__//

__Wide-flange__ Sizing calculation: (30' x12)/16=22.5= W24x94 Weight per (//circular bay//) bay: (94 lbs./ln.ft.)(113 ln.ft.)= 10.62 k/bay

__K-series joist__ Spacing 3’ on center sizing calculation: (30’x12)/20=18= 18k6 Weight per typical bay: (8.5 lbs./ln.ft.)(300 ln.ft.)= 2.55 k/bay

__Deck Slab (//for floor plates//) size: 4” thick__ (//includes seating floor space//) Weight per typical bay: (2,122 sq. ft.)(4/12)(0.150)= 106 k/bay

__Deck Slab (//for roof//) size: 4” thick__ Weight per typical bay: (2,122 sq. ft.)(4/12)(0.150)= 106 k/bay

__Circular (//cast in place//) concrete beams__ (166' (circumference))(2beams)(5'6" high)(1' thick)(150 lbs. per cu.ft.)=273.9 k

__Concrete walls (//combined weights)//__ (18'6" high)(6' long)(1' thick)(4 walls)(150)=66.6 k (25' high)(6' long)(1' thick)(4 walls)(150)=90k

__Total Dead Loads per typical bay:__ 655.67 k/circular theatre total (655.67k)/(2,122 sq.ft.)=308 lbs per sq. ft.
