Steel grid structures are spatial structures formed by connecting multiple members through nodes in a certain grid pattern. The basic units that constitute a grid structure include triangular pyramids, triangular prisms, cubes, truncated quadrilateral pyramids, etc. These basic units can be combined into planar shapes such as triangles, quadrilaterals, hexagons, circles or any other form. It has the advantages of spatial force application, light weight, high rigidity and good seismic performance. It can be used as the roof of buildings such as gymnasiums, theaters, exhibition halls, waiting halls, stadium grandstand canopies, aircraft hangars, and bidirectional large column grid structure workshops. The drawback is that there are a large number of members converging at the nodes, and the fabrication and installation are more complex than those of the planar structure.
