effective length of knee braced columns
effective length of knee braced columns
(OP)
Is there a reference someone can point me at that has a method for determining the in-plane effective length of knee braced columns? It seems that it would be conservative to use K=2 times the full length of the column, but that's how I would do it without having a better procedure. The column in question is steel, one-story, with an actual length of approximately 21'.

Each are two separate design checks (in the plane of course) with a single check out-of-plane.
So the k for the lower in-plane check would be 2.0 with the L being the length from the ground to the brace intersection.
The k for the upper segment would be 1.0 (assuming pinned end at beam) and the length L is the length from the brace to the beam.
