RCC Column Design (Axial Load)
Structural IS 456:2000~3 min
Design a short RCC column for axial load and uniaxial bending as per IS 456:2000.
Formula
Pu = 0.4 × fck × Ac + 0.67 × fy × Asc
Input Parameters
Results
Gross Area (Ag)
1,20,000mm²
Steel Area Required (Asc)
-1,231mm²
Steel Percentage
-1.03%
Step-by-Step Method
- 1Gross area Ag = b × D.
- 2From Pu = 0.4 fck Ac + 0.67 fy Asc, solve for Asc.
- 3Check steel percentage: 0.8% ≤ p ≤ 6%.
Engineering Notes
- •Minimum steel = 0.8% of Ag (IS 456 Cl. 26.5.3.1).
- •Maximum steel = 6% of Ag.
- •Minimum column dimension = 200 mm.
