Steel structure buildings are made entirely of steel, mainly composed of steel beams, columns, trusses and other components made of section steel and steel plates. The components are connected by welding, bolts and rivets. Compared with traditional buildings, they have the characteristics of light weight and simple structure, and are widely used in many fields.Features and Applications of Different Types of Steel Building StructuresPortal Frame StructureFeatures: The force is simple, the force transmission path is clear, and the construction speed is fast. Applications: It is widely used in industrial and civil buildings, such as industrial plants, commercial facilities, cultural and entertainment public facilities, etc. For example, some small and medium-sized factory buildings and community activity centers may adopt the portal frame structure.
Frame Structure Features: It is flexible and can form a larger space. Applications: It is suitable for multi-story and high-rise buildings, such as commercial office buildings, shopping malls, conference centers, etc. For instance, many urban office buildings and large shopping malls are often built with steel frame structures.Truss StructureFeatures: It uses small cross-section tubes to form larger cross-section components. Applications: It is often used in industrial and civil buildings with large spans or heights, such as large-span roofs, bridges, towers, marine oil production platforms, etc. Famous examples include some large stadium roofs and long-span suspension bridges.Grid Structure Features: It is a high-order statically indeterminate space structure composed of many rods according to certain rules, with small space stress, light weight, high rigidity and excellent seismic resistance.Applications: It can be used in gymnasiums, exhibition halls, gas stations, hangars, etc. For example, the roofs of some large gymnasiums and exhibition centers often adopt grid structures.
