A tie beam is a horizontal structural element used in construction to connect two vertical supports, such as columns or walls. Its primary purpose is to resist tension forces and prevent the supports from spreading apart. Tie beams are commonly found in buildings, bridges, and other structures where stability is essential. In addition to providing structural support, tie beams can also help distribute loads evenly across the structure. They are often made from materials like wood, steel, or reinforced concrete, depending on the specific requirements of the project. Properly designed tie beams contribute to the overall safety and durability of a structure.
