Modélisation & Structure RF-IMP RSTAB

I have problems with the definition of equivalent imperfections in RSTAB. Which factors do I have to consider in a correct input?

Réponse

In general, you have to pay attention to the following:

  • The members must have the same member rotation.
  • The direction for the input of imperfections is related to the local axes y and z. A relation to the principal axes u and v is also possible in case of deviating principal axes.
  • It is also possible to influence the position by a change of signs for the imperfection value.

Therefore, when defining imperfections, it is often useful to display the local member axis systems: select a member by right-clicking it and activate the display of the local axis systems in the shortcut menu.
