How to reduce the load on the foundation of a buckle scaffold
(1) The buckle scaffold has high strength and good material properties. Compared with building materials such as concrete, bricks, and wood, steel has high strength and is produced by steel mills with strict quality control. The material has good uniformity and good plasticity and toughness. The high strength of steel makes it suitable for constructing large-span and load-bearing structures. The uniformity and good plasticity of steel materials ensure that steel structures will not suddenly fail due to overloading under normal conditions. They can adjust internal forces and redistribute them by increasing deformation, providing a buffer space for structural reinforcement and strengthening. The excellent toughness of the buckle type scaffold makes the steel structure suitable for working under dynamic loads. Its good energy dissipation capacity and ductility give the steel structure superior seismic performance, making it particularly suitable for various structures in earthquake resistant zones.
(2) Compared with building materials such as concrete, bricks, and wood, steel structures are lighter in weight. Although steel has a higher density, its strength is much higher. The ratio of material mass density to strength is (1.7-3.7) × 10 '/m, while the ratio of reinforced concrete is about 18 × 10/m, so the constructed structure is relatively light. Using structures of the same span to bear the same load, the weight of a buckle type scaffold is 1/4 to 1/3 of that of a reinforced concrete roof truss, and the weight of a cold-formed steel roof truss is even close to 1/10 of that of a reinforced concrete roof truss. The self weight of a steel structure building is about 1/2 to 3/5 of that of a concrete structure building of the same height, and the cross-sectional area of steel structure columns is reduced by about half compared to that of concrete structure columns, effectively increasing the usable area of the building. Steel structures are lightweight, providing convenient conditions for their installation and transportation, while reducing the load on the foundation and lowering the cost of the foundation and its components.
