Is stiffener plate reduce slenderness?
Is stiffener plate reduce slenderness?
(OP)
Hi all, I want to ask about the usage of stiffener.
I have a very long column (L=10660mm). I use the IWF 400x200x8x13.
When I calculate the major axis and minor axis slenderness. I found that if K=1,L=10660,and ry=45.68, the (kl/r) is 233,33 (above 200). It is not allowed since {kl/r) < 200.
If I use stiffener plate, can I reduce the length by the half (10660/2=5330) if I put the stiffener at the middle of the column?
Would you give me any suggestion for this except using bigger IWF section?
Thanks

I like to debate structural engineering theory -- a lot. If I challenge you on something, know that I'm doing so because I respect your opinion enough to either change it or adopt it.
