Flexural bending of steel angle section

[aaro]

I am wondering how to determine what the moment resistance is of a L2x2x3/16 with one leg horizontal, in compression, and laterally restrained, with the other leg vertical. I have a uniformly distributed load along a simply supported span. What particular considerations are there with an unsymmetrical section as this?

Dun dun dun, you better have not caught 40818 in a bad mood or he is going to blast ya in this thread (as he has on one of my threads a while ago)

aaro,

best to talk to your supervising PE about this one.

aaro,

I think that your question does have a merit. If an angle is in bending, the resultant tension and compression forces will not act in the same line. Which may mess up the stress distribution a little bit.

If your angle has adequate bracing, I think using .6*Fy will be more appropriate.

Look in the AISC Manual (9th or 13th Edition). It is fully covered.

it is on page 5-311 in the green book and page 16.1-57 in the 13th edition manual
