coped channel flexural capacity

[MelStud]

I am trying to calculate the flexural capacity of a coped C8x11.5 (coped only at top flange) per AISC manual 14th Ed. I am having trouble using the equations/tables provided in the manual since the Snet seem to be only for W shapes. Also, when calculating the Fcr, what if I get a value greater than Fy? Should I take Fy=Fcr then?

You might not be able to use tables but Sx should be calculated in the usual way, considering the material remaining after the cope is accounted for.

Also, when calculating the Fcr, what if I get a value greater than Fy? Should I take Fy=Fcr then?

Yup, should be the lesser of the two values.


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.
