The beam column connections expected to resist and transfer end reactions only are termed as shear connections or flexible connections. These permit free rotation of the beam end and do not have any moment restraint. Bracket connections, seat connections (unstiffened and stiffened) and framed connections are of flexible type.
The other type of connections which do not permit any relative rotation between the beam and column and are expected to resist moment in addition to end reactions are termed as moment connections or rigid connections. For cantilever arm both moment and end reaction is to be transferred without rotation and therefore rigid connections would be the best choice. Clip angle connection, split beam connection and bracket connection (end plate connection) are rigid connections.

A cantilever arm is to be attached to a column. Which one among the fo...
The best connection for attaching a cantilever arm to a column is an end plate connection.
Reasoning:
- An end plate connection is a type of bolted connection that involves welding an end plate to the end of the cantilever arm and bolting it to the column. This type of connection provides excellent strength and rigidity, making it suitable for high loads and moments.
- Compared to other types of connections, such as framed or seated connections, an end plate connection has the advantage of being easier to fabricate and install. This results in lower costs and faster construction times.
- While a stiffened seated connection can also provide good strength and rigidity, it requires additional welding and fabrication, which can increase costs and construction time.
- A framed connection, on the other hand, is typically used for connecting beams to columns or other beams, and is not well-suited for cantilever arms.
- Therefore, an end plate connection is the best choice for attaching a cantilever arm to a column.
Overall, the choice of connection type will depend on the specific requirements of the project, such as the load and moment capacity, fabrication and installation costs, and construction time.
