Composite columns are structural elements that combine two or more materials to enhance their strength and stability. Typically, they consist of a concrete core surrounded by a steel shell, which allows them to support heavy loads while resisting bending and buckling. This combination makes them ideal for high-rise buildings and bridges. These columns are designed to take advantage of the beneficial properties of each material. For instance, the concrete provides excellent compressive strength, while the steel offers tensile strength and flexibility. As a result, composite columns are increasingly used in modern construction for their efficiency and durability.
