C Channel Formulas
C Channel Formulas
(OP)
I am using 6x13 channel to brace a frame. The channel is braced horizontally between the frame and a concrete wall. I can't seem to fit a C channel into the formulas in ASD or AISC code.
Any suggestions?

RE: C Channel Formulas
Flexural buckling (Fey) about the weak axis can be checked using equation A-E3-11 in the appendix of the 1999 AISC LRFD.
Flexural torsional buckling (Fexz) can be checked using equation A-E3-6.
The minimum of Fey and Fexz should then be used to calculate lamda for use in the appropriate equation (A-E3-2 or A-E3-3) depending on the local buckling properties.
Lamda is then used in equation A-E3-1 to calculate the final strength.
