Compared with traditional buildings, steel - structure buildings represent a new architectural approach, constructed entirely of steel. These buildings primarily consist of components such as steel beams, columns, and trusses, crafted from section steel and steel plates, and joined through welding, bolting, or riveting.

Owing to their lightweight nature and straightforward design, steel - structure buildings have found extensive applications in large factories, stadiums, super - high - rise buildings, and other sectors. They come in various types, including portal rigid - frame, frame, truss, and grid structures.

Features and Applications of Common Steel - Building Structures

Portal - Frame Structure: With a straightforward force - bearing mechanism and a clear force - transmission route, it allows for swift construction. This structure is widely adopted in both industrial and civil projects, like factories, commercial complexes, and cultural or entertainment venues.

Frame Structure: Characterized by its flexibility, it can generate relatively spacious interior areas. It is commonly utilized in multi - story and high - rise buildings, such as office blocks, shopping centers, and conference facilities.

Truss Structure: This structure employs small - cross - section tubes to form larger - cross - section elements. It is frequently used in industrial and civil buildings that require large spans or significant heights, such as large - span roofs, bridges, towers, and offshore oil rigs.

Grid Structure: As a high - order statically indeterminate space structure composed of rods arranged according to specific rules, it offers low spatial stress, light weight, high rigidity, and excellent seismic resistance. It is well - suited for the construction of gymnasiums, exhibition halls, gas stations, and aircraft hangars.
