Lateral frame question
Lateral frame question
(OP)
Does the 2006 IBC or current AISC restrict the use of knee brace frames? I think I've seen comments on KBMRF's before, but did not know if they are disallowed now. Any direction to technical info for this would be appreciated.

"Knee-braced frames function as moment-frame systems and should be treated as indicated in Section C1.3b. Eccentrically braced frame systems function as combined systems and should be treated as indicated in Section C1.3d."
I assume your question pertained to steel structures, for, as far as I know, there is no restriction to the use of Knee braces for wood construction, be it porches, pole structures and the like.
