The characteristics of truss structure and grid

The advantage of the truss is that the rods mainly bear tension or pressure, which can give full play to the role of materials, save materials and reduce structural weight. The truss structure is developed on the basis of the grid structure. Compared with the grid structure, it has its unique advantages and practicability. The amount of structural steel is also more economical.

The grid has the characteristics of space stress, light weight, high rigidity, and good seismic performance. The disadvantage is that the number of rods converging on the node is large, and the production and installation are more complicated than the planar structure.
