[SKJ25POL]

My memory is rusty
Can somebody please give me the steps how to calculate reduced strength od a simply suppoet beam due o drulling a hole in botrom flange

Thank you

If there is an example from any text book that will be helpful

If you happen to have a copy of AISC handy, you're looking for section F13.1

(and in case it's not handy,

Dear Lomarandil (Structural),
Thank you is this section on the AISC 9th Edition too?
Is anywhere in AISC 9th Edition stating about holes in flange of beam for bolt and whats negligable and whats not?

Thank you

Basically, it just comes down to this: if the net section works at the steel rupture strength (Fu), you're good.

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.

Oh boy. That is quite rusty.
