Which type of connection is characterized by both bolted and welded components?

A moment connection is characterized by both bolted and welded components, allowing it to effectively transfer bending moments between structural elements. This type of connection is essential when dealing with forces that create significant moments or rotations at the joint, ensuring structural integrity during events such as high winds or seismic activity.

In a moment connection, the combination of bolts and welds creates a robust joint that can accommodate both axial loads and lateral forces, facilitating the rigid connection necessary for maintaining the stability of framed structures. This is particularly important in multi-story buildings or structures where lateral stability is critical.

In contrast, shear connections primarily handle shear forces and may not have the capacity to resist moments effectively. Flexible connections can allow for some degree of movement and aren't designed for the same level of rigidity, while braced connections typically focus on providing stability through diagonal elements and don't incorporate the same joint behaviors as moment connections.
