Single angle allowable bending stress based on ASD method
Single angle allowable bending stress based on ASD method
(OP)
I tried to attach a pic of the problem it didnt accept ???
However it is an equal leg angle vertical leg toes up
Load is applied on tip of cantelever
Load is due to attachment of girt to horizontal leg by two bolts
I dont know if that triger a biaxial bending? Torsion ? And how to design it based on ASD 9 edition?
Thank you for ur help






RE: Single angle allowable bending stress based on ASD method
Without the picture it's hard to tell but it sounds like it's predominantly going to be simple flexure without much biaxial bending or torsion. That picture would definitely help. Look in section F9 of the specification of 14th edition AISC manual.

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.

I agree with the previous comments, you should use the latest edition of AISC to design this. With their lack of symmetry and sensitivity to where you load them, angles are tricky things. Just dividing the moment by the section modulus and checking that that is less than the yield strength divided by a factor of safety doesn't get it.
