A horizontal beam is a structural element that spans horizontally between two supports. It is commonly used in construction to support loads, such as roofs or floors, and can be made from various materials, including wood, steel, or concrete. The design of a horizontal beam ensures that it can withstand bending and shear forces while maintaining stability. In engineering, horizontal beams are essential in creating frameworks for buildings and bridges. They work in conjunction with vertical elements, like columns, to distribute weight evenly. Properly designed horizontal beams contribute to the overall safety and durability of a structure, making them a critical component in architectural design.
