In contrast to traditional buildings, steel structure buildings offer a modern design where the entire framework is constructed from steel. The structure mainly consists of steel beams, columns, trusses, and other components made from structural steel and steel plates. These parts are joined together using welding, bolts, or rivets. Steel structures, with their lightweight and efficient design, are commonly used in large factories, stadiums, skyscrapers, and other applications. The main types of steel building structures include portal rigid frames, frame structures, truss structures, and grid systems.Characteristics and Uses of Common Steel Building Structures:Portal Frame Structure: This design features a straightforward load distribution and a clear path for force transfer, allowing for faster construction. It is widely utilized in industrial, commercial, cultural, and recreational buildings, as well as public facilities.Steel Frame Structures: Steel frames offer versatility and the ability to create larger open spaces. They are frequently employed in multi-story and high-rise buildings, such as office complexes, shopping malls, convention centers, and similar structures.Steel Truss Structures: These structures use small-section tubes to form larger components, ideal for buildingsrequiring large spans or height. Steel trusses are commonly used in applications like large-span roofs, bridges, towers, and offshore oil platforms.Steel Grid Structures: A highly complex, statically indeterminate system made of interconnected rods, these structures have low stress, lightweight properties, and high rigidity. They also offer strong seismic resistance and are used in large-span roofs, such as those found in sports arenas, exhibition halls, fuel stations, and hangars.
