Aluminum Design - Unbraced unequal leg angles in bending

[jjl317]

I am working through the US based Aluminum Design Manual ADM (using 2015 version, though not sure if this section has changed much over the various versions) to determine the allowable bending moments for unbraced unequal leg angles. The ADM does include a number of worked out examples, unfortunately nothing similar to this. Based on previous research here, I found the "Single Angle Design Guide" from McNulty, which walks through in great detail this for steel, but not for aluminum (though it does appear to use a similar approach).

Does anyone know of a textbook or other publication that might have a worked out example for this?

If not, does someone happen to have a completed calculation (PDF?) that they might have done and might be willing to share, for comparison?

Plus, does anyone know where I could locate a copy of the spreadsheets originally provided with the McNulty guide? I ordered the book new, but it didn't include the files, and I tried to reach out to him via LinkedIn and gotten no answer?

For context - custom vertical angles supporting architectural panels, 16" to 32" on center horizontally, spanning 24" to 30" vertically.

They have examples for unsymmetrical sections in flexure also 'open unsymmetrical shapes in flexure'. This should work for your unequal angle leg.

Unless I am missing something, Single angles are addressed in a different section (F.5) that other open unsymmetric shapes (F.4.2.5), and the approach looks even more complicated (though it may be that F.5 are just more specifically defined versions of F.4.2.5).

At this point, I have roughed out analysis, and am really just trying to ensure I am not missing something.
