The force principle of grid structure

In the grid, the rods mainly bear the tension or pressure, that is, the axial force. No reason, depending on the structural form, the rods can resist the moment generated by the load under the axial force. Theoretical calculations and experimental results have proved this.

The grid structure can be divided into two types: flat grid and curved grid.
There are many flatbed grids. Its advantages: space force system, rods mainly bear axial force, reasonable force, and material saving; good integrity, rigidity, stability, good seismic performance, and can hang cranes; rod types Less, suitable for industrial production.
The flat grid can be divided into two types: cross truss system and pyramid system.
The ratio of the height of the grid to the short span is about 1:15.

The installation method of the grid structure can be divided into two types: high-altitude assembly and overall installation.
