Steel columns and beams generally use welded H-shaped steel, which can be changed arbitrarily according to design requirements.
It is prefabricated in the factory and can be assembled directly on site.
The connection between the steel column and beam has two forms:
1). Rigid connection
The rigid connection is the connection of high-strength bolts at the web and welding on the upper and lower flanges;
2). Hinged connection
Hinged connection refers to the high-strength bolts fixed at the web and upper and lower wings. A connection form that does not require welding.
The steel frame structure system refers to a frame structure composed of steel beams and steel columns along with the longitudinal and transverse directions of the buildings. The steel beams and steel columns form the structural system that bears and resists lateral forces.
There are three forms of a rigid connection between beam and column.
1) Beam flanges, webs, and columns are all fully penetration welded, that is, fully welded nodes;
2) The beam flange and the column are full penetration welded while beam web and column bolted, that is, the welding and bolts mixing joint;
3) The flange and web plate of beam, and column are all bolted, that is, fully bolted nodes;
2.Beam and column hinged connection
The hinged connection between beam and column is divided into web plate of beam connection only; flange plate of beam connection only.
