Steel structure is a structure composed of steel materials. It is one of the main types of building structures. It is mainly composed of beam steel, steel column, steel truss and other components made of section steel and steel plate.
The foundation of steel structure building is generally a separate foundation, and a connecting beam is added in the middle of the foundation. Steel structure buildings generally have frame, plan truss structure, spherical grid, cable membrane, light steel structure, tower and mast and other structural forms. When building, you need to choose the appropriate structure according to the actual use.
Welding seams, bolts or rivets are usually used to connect the members or components of steel structures. Because of its light weight and simple construction, it is widely used in large plants, venues, high-rise and other fields. Steel structures are easy to rust. Generally, steel structures should be derusted, galvanized or coated, and should be maintained regularly.
The material selection of steel structure needs to ensure the bearing capacity of the bearing structure and prevent brittle failure under certain conditions, which is comprehensively considered according to the importance of the structure, load characteristics, structural form, stress state, connection method, steel thickness, working environment and other factors.
