Beam structures are essential components in construction and engineering, designed to support loads and resist bending. They are typically horizontal elements that transfer weight from the roof, floors, or other structures down to vertical supports like columns or walls. Common materials used for beams include wood, steel, and concrete, each chosen based on the specific requirements of the project. The effectiveness of a beam structure depends on its shape, size, and material properties. Beams can be categorized into different types, such as simply supported, cantilever, and continuous beams, each serving unique functions in various applications. Understanding these types helps engineers design safe and efficient structures.
