web penetrations in composite steel beams - web buckling limit
web penetrations in composite steel beams - web buckling limit
(OP)
Hi, just wanted to get some feedback regarding exceeding the P0 ratio given in the proportioning guidelines of AISC Design Guide 2, I have a relatively long opening in a beam which exceeds the limit of 6.0 imposed by section 3.7.a.2 (or 5.7 a.2 in commentary). Can this limit be exceeded if web stiffeners are provided each side of web and each side of the opening?
With the exception of this ratio, the hole works.
Thanks!

Basically you need a smaller opening.
Design guide 2 is fairly old advice, if you want something more recent I would recommend the UK SCI guide P355.
