The connection form of the rigidity node of the engineering beam and column processed by the space frame

The structural forms of the space frame connection of the engineering beam and column processed by the space frame are divided into:

1. Full bolted joints in space frameengineering, beam flanges and webs are connected to column flanges with high-strength bolts through T-shaped connectors, but the rigidity of the convenient joints is not as good as the first two connections, and there are not many applications. 

2.When the space frame beam is rigidly connected to the column, the connection bearing capacity of the beam and the column should be checked. Under the pressure and tension of the beam flange, the space frame should check the compression bearing capacity of the column web and the stiffness of the column flange respectively.

3.Fully welded joints, the upper and lower flanges of the beam are grooved and fully penetrated welds, the web is connected with the column flanges by fillet welds, and the space frame is bolted and welded to connect the mixed joints, that is, only the upper and lower flanges of the beam are used. The groove full penetration weld is connected with the column flange, and the web is connected with the shear plate on the column flange with high-strength bolts. This is a more commonly used structural form.
