Display maximum comparison voltage for steel connections in a table

[Maik0501]

Moiny

maybe I am overlooking something, or maybe not.
Is there an easy way to display the maximum comparison stress in a table for the steel connections, i.e., the verification criterion η, especially when the stress already exceeds the elastic range?
Without having to go through each node individually?

I rather accidentally discovered that you can also display the results of the steel connections graphically.

I can't be the only person who initially sees "all green" in the table, only to later realize that the comparison stress actually exceeds the maximum allowable stress.

Hello Maik,

A tabular output of the maximum equivalent stresses or the verification criterion η is unfortunately not provided in the current version. The reason for this is that the stresses in plate design are not directly used as a failure criterion.

Even if von Mises stresses locally exceed the yield strength, the verification is still considered fulfilled. The design is based on an isotropic-plastic, bilinear material model, where it is not the stress, but the plastic equivalent strain that is decisive.

Therefore, the comparison between the following is crucial:

• existing plastic strain

• allowable plastic strain

The limit value of this plastic equivalent strain is 5% by default according to EN 1993-1-5, Annex C. Only when this value is exceeded is the verification considered not fulfilled.
