The best way to describe rigid frames is to compare them with pin-ended braced structures. The horizontal beams in a braced frame are subject to ‘bending’ when a …

What are Moment Connections? REVISIONS TO PAGE Duplicated text removed At first glance, a moment-frame appears to be a simple post-and-beam construction With a braced-frame these lateral forces are absorbed by the bracing system, which transmits those forces through the diagonal members, into the vertical columns, and into solid ground via the foundations. The best …
