Joist design in Elements
Just FYI, when you run a design on a structure that uses open-web steel joists in RAM Elements 13.4.0.164, you may get a status message like the screenshot below indicating that Elements has designed...

Hi Kris, can we instruct the program to use the geometric axes instead of the principal axis?

What version are you using? There was a change at one point that was made to report moments based in the stronger principle axis rather than the numbered axis and it causes some confusion. The way to...

Seth's response is correct.The member forces are referenced with respect to the principal axes and not the local member axes. For double angles with the short leg back-to-back, the moment of inertia...

If you model a wall below instead then you can get the wall total resultant reaction if that helps.

Seth and Karl, I am using 13.4.0.177 (latest). It is confusing to know when Ram is using Local Axis (2-2, 3-3) or major/minor principal axes. Is the major principal axis always 3-3 and the minor...

Yes you can actually force the software to design as per the geometric axis for angles. Depending on the code that you are using, there are usually design parameters that allow you to do that. For...
