Hi,

The Joint2d element has been supported by stko. But, I have no idea how to create the geometry and assign joint2d to the beam-to-column panel zone.

Further, is it possible to implement joint3d to stko? It will be useful in the analysis of 3d structures.

Looking forward to hearing from you ...

Hi,

I defined an ElasticBilin material with optional parameters. But the 'Write Input File' command returned an error 'name 'EN2_at' is not defiend'. Looking forward to your response.

Thanks, Luis!

It works!

I am sorry that the model did not work after I defined the recorder in the analysis step.
Yes, I have checked your example model. My model has the same analysis steps as the example one. But the result file still has no vibration mode output.

The eigenvalue analysis is defined following the gravity analysis.
In the postprocess, the gravity analysis results can be shown and the eigen analysis result .txt file is generated, while the mode of vibration can not be shown in the postprocess.

Mode of vibration has been selected in the recorder ...

Hi,

There are several node-to-node zero-length elements in my model. How to extract the element end force-relative displacement data in the post-process?

Best regards.
