Display maximum comparison voltage for steel connections in a table

Hello Maik, :waving_hand:

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.

Further information can also be found in our online manual:
