Steel beam connections may be necessary for pillars, slanted joints and segment networks. There are a wide range of connections which are classified into two groups: framed and sealed connections.
For framed connections, the beam is linked to a supporting steel part via fittings. For sealed connections, the beam is positioned on the seat, similar to how it would be with a masonry wall.
Read on to find out more about steel column and beam connections.
Welded framed steel beam connections
Welded frame connections will vary in their capacity depending on their size. The connection weld is subject to stress resulting from loads on the beams, which will affect the pattern of the weld. In fabricating these connections, it’s necessary to consider how stress will affect them. The welding is carried out partly in the field, which can be challenging, as it’s difficult to complete welding when subject to the elements.
Welded seat steel beam connections
This process uses fasteners rather than bolts for the connection. The load on the beam will affect the weld pattern and create stress. Similar to welded frame steel beam connections, these stresses need to be considered during fabrication. Stiffened seats are used for large loads, whereas unstiffened seats are used for smaller loads.
Bolted frame connections
In this type, the steel beams are connected to supporting elements like columns and girders via a web connection. This connection is designed to place the load at the beam’s ends. You should always carefully consider the strength of fasteners and base materials when using this connection.
Bolted seated connections
There are two primary types of bolted seated connections: stiffened and unstiffened. With beams that have large reactions, a stiffened seat connection is recommended because it has the capacity to resist significant force. An unstiffened seat connection is restricted because of its limited capacity for bending at the seat angle leg. The biggest advantage of seat connection is that the steel beam can be made more cheaply and that the seat provides immediate support when the structure is being erected.
Special steel beam connections
This type is most often utilized when the structural elements make it impossible to use standard connections. One example is when the intersecting angles are different to a specific degree, resulting in the beam centers being offset from the centers of the columns. Special connections include single web plate, one-sided framed, balanced web plate and others.
End plate steel beam connections
End plate connections are not suited for tall steel structures and must be fabricated very carefully and accurately. There are several different types of end plate connection that are used for various applications including semi-rigid, rigid and flexible.
