Designing with HSS: Moment Connections 101

on February 13, 2015

Designing with HSS can be a complex concept for the most experienced engineer or fabricator. In fact, it’s likely that you have experienced some confusion while designing with HSS and the connections needed to maintain their structural integrity.

We want to change that. We want to educate industry professionals about the benefits of using HSS in your projects, in addition to some challenges you might encounter. In this installment of our Designing with HSS series, we’re talking about moment connections.

To begin, let’s take a moment to get reacquainted with moment connections…

5 Things You MUST Know About Moment Connections

  1. Moment connections are used with rigid frames to resist lateral loads, such as wind or seismic loads.
  2. Fully restrained connections maintain the defined angles between connected members at strength limit states.
  3. Moment connections develop continuity and rigidity between a beam and a column.
  4. Square HSS columns are ideal for use in moment frames subject to bi-axial loads.
  5. Rigid frames provide clean columns and wide-open efficient spaces.

To learn more about what you must consider while designing with moment connections, watch the video below:
