Compared to traditional buildings, steel - structure buildings introduce a novel architectural concept, being entirely built from steel. Their main components, such as steel beams, columns, and trusses, are made from section steel and steel plates, and are connected via welding, bolting, and riveting.
Thanks to their lightweight and simple design, steel - structure buildings are widely applied in large factories, stadiums, super - high - rises, and various other fields.
The types of steel - building structures include portal rigid steel frames, frame structures, truss structures, and grid structures. Here are their features and applications:
Portal Frame Structure: It has a simple force - distribution system and a clear force - transmission path, enabling rapid construction. Commonly used in industrial and civil buildings, like industrial plants, commercial areas, cultural sites, and entertainment facilities.
Steel Building Frame Structures: Offering flexibility, they can create larger spaces. Widely used in multi - story and high - rise buildings, such as commercial offices, shopping malls, and conference centers.
Steel Truss Structure: By using small - cross - section tubes to form larger - cross - section components, it is often employed in industrial and civil buildings with large spans or heights, like large - span roofs, bridges, towers, and offshore oil platforms.
Steel Grid Structure: This high - order statically indeterminate space structure consists of numerous rods arranged by specific rules. It features low space stress, light weight, high rigidity, and excellent seismic resistance, and can be used for gymnasiums, exhibition halls, gas stations, hangars, and other large - scale facilities.
In summary, steel - structure buildings boast multiple advantages, including strength, durability, and efficiency, making them an ideal option for a wide variety of construction projects.
