Displacement Control for two nodes

[Syun]

Dear STKO Team,

Thank you for your response — I was able to successfully plot the hysteresis loops for the joints!

I apologize for reaching out again, but I am currently trying to extract the story shear forces for each floor of my model and have been encountering difficulty identifying which results to use.

So far, I have tried exporting nodal reaction forces as well as material stresses at Gauss points, but neither seem to provide the story shear data I’m looking for.

Would you be able to offer any suggestions or guidance on how I might obtain this type of information?
I sincerely appreciate your continued support and look forward to your reply.

Dear STKO Team,

Thank you very much for your response. I read through the forum thread you shared, but I’m still unsure about the exact steps needed to extract story shear data.

Currently, I tried enabling section.force in the recorder and intended to extract the shear forces of columns by selecting Gauss points in the post-processing software. However, I noticed that Gauss points only appear on the wall elements, and not on the columns (shown in figure 1). As a result, I’m unable to select the Gauss points of the columns to obtain their internal force data.

For your reference, the columns in my model use forceBeamColumn elements with fiber sections.

I’ve attached both my model and the corresponding result file. I would greatly appreciate it if you could kindly help check whether I may have missed something in the settings that prevents the Gauss points from being generated for column elements.

Looking forward to your advice. Thank you again for your continued support!

This is because you selected section.force on surfaces. On the dropdown menu of the results you will find another section.force result for beams.

Another suggestion: discretize the wall. 1 element per wall is not enough. A shell is not like a beam, it needs to be discretized in the plane direction.

Finally, the post I references tells you to use a tool called section cut integrator. to integrate end-node forces and sum them up in a cut plane
