Large-span steel structures refer to roof structures with a span of ≥ 40 meters. They mainly use steel as the load-bearing material and achieve the architectural effect of large spaces, few columns or no columns through spatial systems such as grid structures, shells, trusses, suspension cables, and membrane structures. These structures have the characteristics of light weight, high strength, large spatial stiffness, good seismic performance, and fast construction speed. They are widely used in sports venues, exhibition centers, airport terminals, large industrial plants, etc.
Main Structural System and Characteristics
1. Grid structure
A double-layer or multi-layer flat-shaped grid structure composed of multiple rods connected through nodes, with high spatial stiffness, good integrity, and uniform force distribution. It is suitable for large-span roof structures of regular planes such as large stadiums and exhibition halls.
2. Shell structure
A curved grid structure, divided into single-layer and double-layer shells, combining the characteristics of shell and grid structures. It has a beautiful appearance and high material utilization rate, and is suitable for complex curved surface buildings.
3. Truss structure
A triangular unit system composed of inclined rods, beams, and nodes. It has good structural stability and strong seismic performance, and is suitable for large-span stadiums, exhibition halls, and industrial plants.
4. Cable structure
A structure mainly composed of high-strength steel cables, transmitting loads through the tension of the cables. It is lightweight, has a large spanning capacity, and is suitable for airport waiting halls and large exhibition centers.
5. Membrane structure
Covered with flexible membrane materials, forming a stable curved surface through pre-tensioning. It is extremely lightweight, has good light transmission, and is suitable for temporary or buildings with high requirements for lighting.
