Concrete Volume
0.37 cu yd
Concrete Volume vs Width / Diameter
Formule
Concrete Column Volume
Rectangular: V = W x D x H
Round: V = pi x (D/2) squared x H
Convert all dimensions to consistent units. Add 2 ft per bar for lap splices and embedment into the footing. Vertical rebar count must be at least 4 for rectangular columns and 6 for round columns per ACI 318.
Exemple Résolu
12 x 12 in rectangular column, 10 ft tall, 4 bars.
- 01Area = 12 x 12 = 144 sq in = 1 sq ft
- 02Volume = 1 x 10 = 10 cu ft = 0.37 cu yd
- 03Rebar = 4 x (10 + 2) = 48 ft
Questions Fréquentes
What is the minimum reinforcement for a concrete column?
ACI 318 requires a minimum of 1% of the gross cross-section area in vertical reinforcement and a maximum of 8%. Ties or spirals provide lateral confinement.
How are ties spaced on a concrete column?
Standard tie spacing is the smallest of: 16 bar diameters, 48 tie diameters, or the least column dimension. Typical residential columns use No. 3 ties at 12 inches on center.
