Braced and unbraced columns
Braced and unbraced columns
(OP)
If i want to design a nornal framed structure comprising of beams and columns without having anything particular for resisting horizontal forces apart from beams and columns. How should I treat the columns, braced or unbraced?
Thanks in advance.

RE: Braced and unbraced columns
If you add a diagonal brace, you can design as non-sway columns.
I assume you mean non-sway or sway when you say braced or un-braced.
k>1 for sway, k<=1 for non-sway.

Theorectically, in a moment resisting frame, the inflection point(s) could also be considered as a lateral brace, but some would disagree. So it would be conservative to ignore that.

If lateral forces are resisted through bending of the members (as in a moment frame), then it's unbraced.
