I am working with this bridge which has stiffeners (steel beams) between girders.
In the results, two of them seem to grow somehow when changing the scale.
I am wondering why this enlargement occurs only for two of them and not all of them.

Scale 1.0:

Scale 400:

 

Is it because the deformations?

Transversal:

But the vertical is even larger and is not in any of those:

Hi,

Please check if the parts are properly connected. You may try running a modal analysis as well. If the parts are shell bodies and bonded then check if you have used MPC algorithm for the contact. MPC algorithm gives proper result display for shell elements.

These are beam elements attached to 3D solids. All connections are the same for all beams and it works properly for the rest.

I have tried the following:

• use MPC as suggested
• extracted the beams again (from zero)
• delete the connection and duplicate from a beam which does not show this issue and assign it to the mentioned beams

but the problem is still there.
