Effective length for out of plane pipe bent column

[DAVE9999]

Pipe bent consists of two columns with three beams (moment connections) between columns. Out of plane it is free (no bracing or tie backs). What is the K factor out of plane? Should I use K=2 like a cantilever or can it be reduced? Thanks for the help

A cantilever would require k = 2.0.

You mean 2.1, right? See Table C-C2.2 in AISC 13th ed, case (e).

2, 2.1, whatever it takes....
