Read multiple points on a line element

[ARPASEVAN]

Hello,

Is there a Python code to provide joint information on a Line Element? For example, the blue member shown below is one piece, and I can read the end joints and all forces, but this doesn't provide much help for internal connections and forces. Is there any other way to get data for each segment?

Below is the a partial code used to read the forces.

sap_model.Results.Setup.DeselectAllCasesAndCombosForOutput()
sap_model.Results.Setup.SetComboSelectedForOutput(com)
frameForces = sap_model.Results.FrameForce("ALL", 2)

Thank You.

Did you see this post?

ETABs API - Steel Beam Design Shear Reactions - Computers and Structures: ETABS

Is there any way to access beam end shear reactions through the API for steel beam design like that of composite beam designs? There is a nice method in composite beam design (DesignCompositeBeam.GetSummaryResults) that returns ReacLeft and ReacRt that does the trick for composite beams...

You can access results for your beam with the code in the post. You can access along stations as well if you like. With this info you could recreate your applied forces.

You could also get all of the joints associated with the blue line and query for any applied loading.

Thank you S&T for your response and link to the post. My output for the blue beam (Frame #3) is shown below. The bays are 10', 10', 20'. I am not sure how to create three segments from this data.

My bad, i thought that this was (3) individual line (frame) segments already broken up.

It would be helpful to see the applied loading to the element and see what you are trying to retrieve. Can you post some more info?

It looks like in your output, there is an applied load at 3.33 ft in, shear jumps from 2.7796 to -0.8089. Is that right/what you are trying to get?
