Definition
Compression strength is the ability of a structural material to withstand compression forces, expressed as the measured maximum resistance of a specimen to axial loading, typically in pounds per square inch (psi).
Purpose
The purpose of compression strength is to determine a material's ability to resist being crushed or shortened under compressive loads, which is crucial for designing safe and stable structures.
Examples of Use
- Concrete's compression strength is tested to ensure it meets the required specifications for building foundations, columns, and beams.
- Structural steel's compression strength is analyzed to design load-bearing elements in buildings and bridges.
- Masonry units, such as bricks and blocks, are tested for compression strength to ensure they can support the loads imposed on walls.
Related Terms
- Tensile Strength: The ability of a material to withstand tension (pulling) forces.
- Shear Strength: The ability of a material to resist shear (sliding) forces.
- Yield Strength: The stress at which a material begins to deform plastically.
Notes
Compression strength is a critical factor in structural engineering, influencing material selection and design calculations. Standardized tests, such as ASTM C39 for concrete, are used to measure compression strength.
