Floor/Ceiling

• dimensions
  • sqft
• dead load
  • pressure
    • flooring: 4 psf  (not mentioned in Phase 1)
    • sheathing/subfloor: 3/4" plywood = 3 x 3/4 = 2.25 psf
    • joist: 2x10 at 16" OC = 2.4 psf
    • drywall: 1/2" gypsum board = 5 x 1/2 = 2.5 psf
    • D = 11.2 psf
    • rim joist: 2x10 @ 28.52 lb/ft³ = 2.748 lb/ft
  • load to joist
    • A_T = 16 in. (1 ft/12 in.) x (14 ft) = 18.67 ft²
    • w_D = 11.2 psf x 16 in. (1 ft/12 in.) = 14.93 lb/ft
  • load to stud in interior wall
    • A_T = 16 in. (1 ft/12 in.) x (7 ft) x 2 sides = 18.67 ft²
    • P_D = D A_T = 209.1 lb
  • load to stud in exterior side wall
    • A_T = 16 in. (1 ft/12 in.) x (7 ft) = 9.333 ft²
    • P_D = D A_T = 104.5 lb
• live load
  • pressure
    • L₀ = 40 psf  (would be 30 psf for sleeping areas, ASCE 7 table 4-1)
  • load to joist
    • A_T = 16 in. (1 ft/12 in.) x (14 ft) = 18.67 ft²
    • w_L = 40 psf x 16 in. (1 ft/12 in.) = 53.33 lb/ft
  • load to stud in interior wall
    • A_T = 16 in. (1 ft/12 in.) x (7 ft) x 2 sides = 18.67 ft²
    • P_L = L A_T = 746.8 lb
  • load to stud in exterior side wall
    • A_T = 16 in. (1 ft/12 in.) x (7 ft) = 11.00 ft²
    • P_L = L A_T = 440.0 lb
• live load
• snow load
• wind load
• seismic load
• deflection limits  (IBC table 1604.3)
  • L/360 for L = 14 ft x 12in./ft / 360 = 0.4667 in.
  • L/240 for D + L  (or L + 0.5D if under dry conditions) = 14 ft x 12in./ft / 240 = 0.7000 in.
