Compressive Stress vs Compressive Force (F)
Direct Compressive Stress
Compressive stress develops when a member is pushed axially.
Formula
sigma_c = F / A
The formula is identical to tensile stress, but the member may also need a buckling check if it is slender. Short, stocky members fail by crushing; long, slender members fail by buckling at a load lower than the crushing capacity.
Example Calculation
A concrete column with 2500 mm^2 effective area under 200 kN axial load.
- 01Convert force: 200 kN = 200,000 N
- 02sigma_c = 200,000 / 2,500 = 80 MPa
- 03For 30 MPa concrete, this exceeds capacity. A larger section or higher-strength concrete is needed.
