The node structure of the steel structure grid should meet the following points:
(1) The force is reasonable and the force transmission is clear. Make sure that the structure of the node is as consistent as possible with the calculation assumptions used to make the node safe and reliable.
(2) Ensure that the intersecting rods intersect at one point and no additional bending moment is generated;
(3) The structure is simple, the production is simple, and the installation is convenient;
(4) Less steel consumption and low cost.
