Compared with traditional buildings, steel - structured buildings represent a new type of construction. The entire building is constructed using steel. The structure mainly consists of steel beams, columns, trusses, and other components made of section steel and steel plates. Connections between components are made by welding, bolts, or rivets. Due to their lightweight nature and simple structures, they find extensive applications in large factories, stadiums, super - high - rise buildings, and other fields. Types of steel - structured building systems include portal rigid - frame structures, frame structures, truss structures, and grid structures. The features and applications of these standard types of steel - structured building systems are as follows:1,Portal rigid - frame structure: It has a simple force - bearing mechanism, a clear force - transmission path, and allows for rapid construction. It is widely used in industrial and civil buildings such as industrial plants, commercial buildings, cultural facilities, and entertainment venues.2,Steel - structured frame system: It offers great flexibility and can create a relatively large interior space. It is commonly applied in multi - story and high - rise buildings such as commercial office buildings, shopping malls, and conference centers.3,Steel truss structure: Small - cross - section tubes are used to form larger - cross - section components. This type of structure is often employed in industrial and civil buildings where large spans or heights are required, such as large - span roofs, bridges, towers, and offshore oil production platforms.4,Steel space frame structures: It is a high - order statically indeterminate space structure composed of numerous rods arranged in a certain pattern. It features low spatial stress, lightweight, high rigidity, and excellent seismic - resistance performance. It can be used in the construction of gymnasiums, exhibition halls, gas stations, and aircraft hangars.
