Data visualization of the RC frame model

[Chaymaa]

Dear STKO teams,

I am trying to learn how to use STKO, that's why I decided to rebuilt the RC-frame model that I’ve found on your YouTube channel (https://www.youtube.com/watch?v=BomvTEn64M8&t=2477s). However, it seems like I don’t get the same results, nor the same visualization of the fiber sections map.

I attached the file, any help would be much appreciated.

Could you be more specific?
I can reproduce a fiber plot:

Hi,
I meant by not getting the same results; not getting the same distribution of strain nor stress. I can’t visualize the deformations too. I’ve tried also to draw the displacement of the master node as shown in the video, but I don’t get the same behavior.

The error in the pushover curve is because you put the wrong Target Displacement (too small).
In the old version of STKO used in that webinar, I was using an increment = 0.1 mm with 1000 steps for a total of 100 mm.

In the current version, it's easier. You should directly input the final target displacement (100 mm in this case).
And now you can also use adaptive time steps for better control of the convergence:

Regarding the fiber plots, if you want to use the old-style, i.e. same size for all fibers, you can do this:
