Re: Mesh in Shear wall

Hello STKO team,

Yes, I found the difference. There was a difference in -GJ value while defining the fiber section. The difference was 1e13 and 1e15.
Now, I am getting the results closer.

Result:

First Second
STKO OpenSees: 0.118367 0.037438
OpenSees with TCL: 0.1183 0.03744

Re: Mesh in Shear wall

Hello STKO Team,
Thank you for the reply.

By intermediate node, I meant I divided the boundary element into 4 parts.

Mesh in Shear wall

Hello everyone,
I modeled a shear wall with boundary elements in STKO and also tried to model the same using TCL script.
In STKO, I modeled the shear wall with the face element and assigned the boundary element to edges (bottom fig). Then the structure is divided into 4 uniform divisions (as global ...

Re: Convergence error

Hello Clarabella,

Thank you for the reply.
I have using OpenSees couple of years and wanted to shift to the graphical interface, and I think the STKO team has developed a great tool.

By model checking, do you mean there is some technique within SKTO to check the model, or is that the service ...

Hello STKO team,

Thank you for the reply.

I tried with higher epsCU, however, that did not change the convergence issue.

Thank you.

Re: Convergence error

Hello Clarabella,

Thank you for your reply.

Yes, I have results for the first 6.27 sec then my model has a convergence issue. I also followed suggestions from the forum and some lecture videos by the STKO team but couldn't solve the problem. (I have attached my displacement output for the first 6 ...

Convergence error

Hello everyone,

I am trying to run a time history analysis of the RCC building with shear walls. My modal and gravity analysis run fine, however, I get the following convergence issue when I run time history analysis. Can anyone suggest a way to trackback this error?

(Here, a warning shows an ...

'NoneType' object has no attribute 'id'

I am trying to do an eigenanalysis of a building, when I run the analysis, I get the 'NoneType' object has no attribute 'id' error. Can anyone suggest me a way that I can solve this issue?

Thank you.
