The grid structure is a spatial structure formed by connecting multiple rods through nodes in a certain grid form. The steel frame structure can be divided into doublelayer platetype grid structure, singlelayer and doublelayer shelltype grid structure. The basic units that make up the steel grid structure include triangular pyramids, triangular prisms, cubes, truncated quadrangular pyramids, etc. These basic units can be combined into flat shapes of triangles, quadrilaterals, hexagons, circles or any other shapes. . It has the advantages of space stress, light weight, high rigidity, and good seismic performance.
Grid structure classification, plate type grid structure is divided into three categories:
1. Composed of a plane truss system, there are four types of twoway orthogonal orthographic grid, twoway orthogonal diagonal grid, twoway diagonal diagonal grid and threeway grid;
2. Composed of quadrangular pyramid units, there are five types of positive quadrangular pyramid grids, positive quadrangular pyramid grids, diagonal quadrangular pyramid grids, checkerboard quadrangular pyramid grids and star quadrangular pyramid grids;
3. Composed of triangular pyramid units, there are three forms of triangular pyramid grid, evacuated triangular pyramid grid and honeycomb triangular pyramid grid.
