Example to Determine Weight of a Concrete Beam Per Linear Foot Using 9″ Slab
Mar 31, 2017
- D = Depth of beam in inches
- W = Width of beam in inches
- L.L. = “Live Load” Placement of Concrete, Hen and Equipment Use 40 lbs. per square foot
- lb/ft2 = Pounds per square foot
- lbs/ft3 = Pounds per cubic foot
- Wt. = Weight of formwork. Use 101 lbs. per square foot (lb/ft2)
- L.L. & Wt. FM. = Use 50 lbs. per square foot (lb/ft2)
- Wt. Conc. = Weight of Concrete. Use 150 lbs. per cubic foot (lb/ft3)
D/12 x Wt. Conc. + L.L. + Wt. FM. x W/12 = Weight of Concrete Beam per Lineal Foot
36 x 150 lbs/ft3 + 50 lb./sq.ft. x 18 = Weight of Concrete Beam per Lineal Foot
450 lbs. + 50 lbs. x 1.5 = Weight of Concrete Beam per Lineal Foot
750 lbs. = Weight of Concrete Beam per Lineal Foot.
