Compression members are structural elements that carry loads primarily through axial compression. They are designed to resist forces that push or squeeze them together, such as columns in buildings or bridges. Common materials used for compression members include steel, concrete, and wood, each chosen for their strength and stability. In engineering, the design of compression members must consider factors like buckling, which occurs when a member deforms under load. Proper sizing and material selection help ensure that these members can safely support the weight they bear, contributing to the overall safety and integrity of structures like skyscrapers and towers.
