TYPES OF STEEL BEAM CONNECTIONS
Bolted framed connections
For these types of steel beam connections, the load at the end of the beam is used to design the connection. When designing a connection, it is necessary to consider the strength, type, and size of fasteners as well as the strength of the foundation materials. At least half of the clear web depth of the beam should be covered by the connecting angle. This specification is made to guarantee that the structure is rigid and stable enough. Bolted framed connections come in a variety of conventional sizes and capacities, as determined by regulations. The goal of a common connection like this is to make the design process go faster. To keep the design as cost-effective as possible, it’s best to employ the bare minimum of connections to sustain the imposed stress.
Bolted seated connections
Stiffened and unstiffened connections are the two types of bolted seated connectors:
If the reaction force at the end of the beam is significant, the stiffened connection type is preferred since it has the requisite strength to withstand these forces. In the event of an unstiffened connection, however, there is a limit to the pressures that may be resisted.
The process of creating seat connectors is inexpensive, and it offers immediate support during construction. Aside from that, they don’t need a lot of main steel detailing. Because the structure with this connection may be destroyed and reused in future projects, these types of steel beam connections are environmentally benign.
Welded seat connections
It’s similar to a bolt seat connection, but instead of bolts, welding is used to secure the elements. This form of connection, like bolt seats, can be classified as stiffened or unstiffened. Small loads are handled by the unstiffened kind, whereas heavier loads are handled by the stiffened type.
Welded seat connections are not environmentally friendly since constructions with this form of connection are difficult to disassemble and install.
Welded framed connections
The connection’s weld is determined by direct shear stress and stress induced by loads on the beam. As a result, these pressures must be taken into account. Because a portion of the welding is done in the field, it might be challenging to accomplish a high-quality weld owing to steel member movement caused by wind or other conditions.
End plate connections
Flexible, semi-rigid, and stiff plate end connections are among the several forms of end plate connectors. To avoid mistakes, this sort of fabrication and cutting must be done with the utmost precision. High construction should avoid end plate connections.
Special steel beam connections
When normal connections aren’t available, they are utilized instead. Bent-plate framed, single web plate, one-sided framed, balanced web plate, and Z-type connections are examples of special connections.
Simple, rigid and semi-rigid connections
Moment connections can transmit forces from the beam sides to the column, and this transfer moment must be accounted for more often than not, since it is generally free of the shear connection required to maintain the beam reaction. Simple, stiff, and semi-rigid connections are intended to support beams and columns exclusively in shear, leaving the ends free to move under load. They offer adequate stiffness to maintain practically constant angles between linked parts in addition to carrying shear.
