Compressive Stress

Compressive Stress vs Compressive Force (F)
सूत्र
## 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.
हल किया गया उदाहरण
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.
अक्सर पूछे जाने वाले प्रश्न
How does compressive strength differ from tensile strength?
Many materials have different capacities in tension versus compression. Concrete is strong in compression (20-50 MPa) but weak in tension (about 10% of compressive strength). Steel has roughly equal tensile and compressive yield strengths.
When do I need to check for buckling?
When the slenderness ratio (effective length divided by radius of gyration) exceeds about 20-30, buckling becomes a concern and the Euler or inelastic buckling formula should be checked.
What is bearing stress?
Bearing stress is a localized compressive stress where one member presses against another, such as a beam sitting on a support plate. It equals force divided by the contact area.
