Frame Structure
The plane shape of the grid is flexible and can be designed into various shapes. According to the different settings of the web members, it can be divided into: cross truss system, quadrilateral cone system, triangular cone system, and other systems. When the chords of a grid are perpendicular to the boundary, it is called a positive grid, and when they intersect diagonally with the boundary, it is called an oblique grid. Many countries around the world have successfully constructed many grid structures in large and medium-sized roofs, such as the expos in Canada and Japan, the Congressional Hall in Chicago, USA, and the hangar in London, UK, with large floor dimensions and relatively economical total steel consumption. The former Soviet Union also used prestressing in the grid structures. In short, grid structure has become one of the most commonly used new structures in the modern world. China has been researching and adopting grid structures since the 1960s. In recent years, due to the rapid development of electronic computing technology, the calculation problem of high-order hyperstatic structures in grid structures has been solved, promoting the rapid development of grid structures in both types and practical engineering applications. At present, it is mainly used in large and medium span public buildings, such as sports halls, hangars, clubs, exhibition halls, and waiting halls. Small and medium-sized industrial plants are also being promoted and applied. The larger the span, the more significant the advantages and economic effects of using this structure.
Light Steel Structure
Light steel structure, also known as light steel structure building system, is a lightweight fully assembled steel structure building mainly composed of high-efficiency structural steel and functional materials such as hot-rolled light H-steel, light welded steel, high-frequency welded steel, cold-formed thin-walled steel, thin steel plates, and thin-walled steel pipes, supplemented by various high-efficiency decorative connecting materials, which can meet the specific functional and spatial requirements of the building.
