What is the structural joint between a column and a beam designed to be rigid called?

1. Beam connection

2. Rigid connection

3. Moment connection

4. Flex connection

The correct answer is: Moment connection

The structural joint between a column and a beam that is designed to be rigid is known as a moment connection. This type of connection allows for the transfer of moments, or bending forces, between the column and the beam, which is critical for maintaining the stability and rigidity of the structure under load. Moment connections are essential in structures that require the ability to withstand lateral loads, such as those caused by wind or seismic activity. Unlike other types of connections that may allow for movement or rotation, a moment connection effectively creates a fixed point, ensuring that the loads are distributed appropriately throughout the structure. This is particularly important in high-rise buildings and other structures where maintaining the integrity of the frame under various forces is crucial for safety and performance.
