I believe most people will plot a point in 3d space, at P, Mx, My for a given neutral axis angle. No need to find the point where they cross, just plot (P, Mx, My) In the gif below, each point on this 3d plot is for a given neutral axis angle of 45 degress.

This code did the trick for me: x = SapModel.Results.Setup.DeselectAllCasesAndCombosForOutput() loadName = "Dead" x = SapModel.Results.Setup.SetCaseSelectedForOutput(loadName) z = SapModel.Results.JointDisplAbs('~64', 1) print(z)

I have never played with editting the $sf file before. You likely could achieve changing point loads to area loads with the SAFE api or maybe even with database tables.

For arguments sake, let's say yes. Technically if you continued the area reinforcing in all directions, option 2 would be even better. I just want to focus on the first critical perimeter for now.

Thanks for that, I was aware of this after watching the Bondy video on punching. I was thinking @bookowski might have something not listed in code

Ok, thanks everyone. Sounds like option 1 is standard in most places. Clearly option 2 provides some benefit to the punching shear, but quantitively let's try to put a number to it. I believe that ACI is trying to figure out the total numbers of bars that cross the failure plane as shown in...

Recently I was working with some really large loads and trying to deal with punching shear on thick concrete elements. I worked the ACI equations for punching shear and I needed (32) #5, bars, (8) legs*4 sides, at my critical perimeter, at a spacing of 6"oc. Traditional examples of punching...

Ah, helps if I could read. Definitely seems like a bug/feature missing from the ETABs API. Please reach out to them and let them know, this will be helpful for the section cutter tool I hope to be working on in the future.

I just checked in ETABs, and I do not see a results.setup.sectioncutselectedforoutput in the api documentation. Title of the post makes me think of ETABs, but then you mention SAP200. Also in ETABs, I do not see an option to turn off results for any section cut, seems like you would always want...

Is this for calc package creation Brad? Lots of times I rip data out of the API to automate graphs and plots outside of ETABs. The plot below ripped out frame location data and forces to make the 3d plot.

You most certainly can get all the forces in a frame elements and the corresponding load combinations.

From an API perspective, I don't think there is a current way to get the named views. I do not see any API functions to work with named views, even in the database tables. You can get the model name with the API though: SapModel = ETABSObject.SapModel #Get the filename of the ETABs model...

Let me know if I understand your question correctly. You broke down you moment 24.86 kip*ft into a tension compression force of 1.65 kip. Do you need to consider the 24.86 kip*ft any more? If this is correct, then no, you do not need to consider the 24.86 kip*ft any more for the design of the...

Damned if we ask the framers to do something complicated, damned if we spec any structural steel. Cant win :)

No jambs in the hung situation. Just add a vertical joint adjacent to the strip window.
