Effective Stiffness of Slender Sections in AS4100
Effective Stiffness of Slender Sections in AS4100
(OP)
Hi all,
I was wondering if anyone was aware of any reference to the effective stiffness of a slender steel section in AS4100.
AS4100 covers element slenderness for capacity calculations, but I cannot seem to find any reference to the effective stiffness to use when calculating deflections. There is a reference in AS4600 so I assumed I would find one in AS4100?
Any help would be appreciated.
Robbie

That being said, a thin wall section (AS4600) is quite a different beast to hot rolled section (AS4100).

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.

My particular example involves sizing the web thickness of a cantilevered tee-section which is being governed by deflection. The architect is after a web as small as possible and I was hoping to get some insight into everyone's thoughts on the design of this?
