Steel - structured buildings stand out as a revolutionary alternative to traditional construction methods, boasting a plethora of remarkable advantages.In a steel - structured building, the entire framework is crafted from steel, with its structure primarily consisting of steel beams, columns, trusses, and other components made from section steel and steel plates. These components are securely connected through welding, bolts, or rivets.One of the most prominent advantages is its lightweight nature. This characteristic not only significantly reduces the dead load on the foundation but also makes transportation and installation a breeze. In contrast to traditional buildings, steel - structured buildings can be erected much more quickly, leading to shorter construction periods. This is mainly due to their simple structures, which allow for pre - fabrication in factories and then on - site assembly.The flexibility of steel - building frame structures is another major plus. They can easily form vast and open interior spaces, providing architects with more creative freedom. This makes them ideal for multi - story and high - rise buildings such as commercial office buildings, shopping malls, and conference centers.Steel - structured buildings also have a wide range of applications. For example, the portal frame structure, with its simple force - bearing and clear force - transmission path, is extensively used in industrial and civil buildings, including industrial facilities, commercial areas, cultural venues, and entertainment public facilities.The steel truss structure, which uses small - cross - section tubes to form larger - cross - section components, is well - suited for buildings with large spans or heights, like large - span roofs, bridges, towers, and marine oil production platforms.The steel grid structure, a high - order statically indeterminate space structure composed of numerous rods in a specific pattern, has low space stress, high rigidity, and outstanding seismic - resistance capabilities. It is commonly used in the construction of gymnasiums, exhibition halls, petrol stations, and hangars.In summary, steel - structured buildings combine the benefits of lightweight design, rapid construction, flexible space - making, and wide - ranging applications, making them an increasingly popular choice in modern construction.
