Steel-structured buildings represent an innovative approach to construction compared to traditional buildings. In these buildings, the entire structure is made of steel, primarily consisting of steel beams, columns, trusses, and other components fabricated from section steel and steel plates. The components are connected using welding, bolts, or rivets. Due to their lightweight and simple design, steel structures are widely used in large factories, stadiums, super-tall skyscrapers, and other sectors. The primary types of steel building structures include portal rigid steel frames, frame structures, truss structures, and grid structures. Portal Frame Structure: This structure is known for its simple load-bearing mechanism, clear force transmission paths, and fast construction speed. It is widely used in industrial and civil buildings, such as industrial facilities, commercial properties, cultural venues, and entertainment-related public facilities.Steel Frame Structure: Steel frame structures offer flexibility and allow for the creation of larger open spaces. They are commonly used in multi-story and high-rise buildings, including commercial office buildings, shopping malls, conference centers, and similar structures. Steel Truss Structure: Using small cross-section tubes to form larger components, the steel truss structure is often used in buildings with large spans or significant height. It is commonly found in industrial and civil projects, such as large-span roofs, bridges, towers, and offshore oil production platforms.Steel Grid Structure: The steel grid structure is a highly indeterminate spatial framework made up of interconnected rods arranged according to specific rules. It features minimal space stress, lightweight construction, high rigidity, and excellent seismic resistance. It is typically used in the construction of gymnasiums, exhibition halls, petrol stations, and hangars.
