MOMENT CONNECTION EXTEND NO HAUNCH

A moment connection refers to a structural connection between two members that allows for the transfer of bending moments, which are rotational forces applied to a structural element. In a moment connection, the members are joined together in such a way that they can transfer moments without significant rotation or deformation.

The term “extend no haunch” typically refers to the design of a moment connection without the use of a haunch. A haunch is an extension or thickening of a member near the connection area, which is often used to improve the load transfer capacity and reduce the stress concentration at the connection.

In a moment connection without a haunch, the connection design relies on other means to transfer the bending moments effectively. This can involve the use of additional bolts or welds, increased plate thickness, or other structural details to enhance the load transfer capacity. The absence of a haunch in the connection design simplifies fabrication and construction, but it may require more careful analysis and detailing to ensure the connection’s integrity.
