Unlike traditional buildings, steel structures offer a more contemporary approach to construction, where the entire structure is composed of steel. These buildings mainly consist of steel beams, columns, trusses, and other elements made from steel sections and plates. The components are connected using welding, bolts, or rivets. Due to their lightweight and efficient design, steel structures are widely used in large factories, stadiums, skyscrapers, and other applications. Types of steel building frameworks include portal rigid steel frames, frame structures, truss systems, and grid frameworks.Features and Applications of Common Steel Building Structures:Portal Frame Structures: These provide simple load distribution, clear force transmission paths, and quick assembly. They are commonly used in industrial and civil projects, including commercial, cultural, and recreational facilities.Steel Frame Structures: These structures offer versatility and the ability to create vast, open spaces. They are often used in multi-story and high-rise buildings, such as office buildings, shopping centers, conference halls, and more.Steel Truss Structures: These utilize small-section tubes to create larger components and are ideal for projects requiring long spans or considerable height. Steel trusses are commonly found in large-span roofs, bridges, towers, and offshore oil platforms.Steel Grid Structures: This advanced, statically indeterminate spatial structure is composed of many rods arranged in a specific pattern, offering minimal stress, lightweight properties, high rigidity, and excellent seismic resistance. They are commonly used for large-span roofs in gymnasiums, exhibition halls, fueling stations, and aircraft hangars.
