A member was divided by several nodes. When I apply the imperfections, each partial member gets its own imperfection.

How can I define an imperfection across all partial members?

回答

If a member consists of several partial members, you need to specify to which objects the imperfection should refer to when defining imperfections. You have the following options to do this:

Members

The imperfection has an influence on one member or independently on several members.

Member List

The imperfection acts on the entirety of the members to be specified in a list. The predeformations and inclinations are therefore not applied individually to a member, but as a total imperfection to all members of the member list. By means of a member list, the imperfections can be applied so as to cover several members without having to define continuous members.

Sets of Members

The imperfection acts on a set of members or on several sets of members. Like for a member list, the parameters are applied to all the members contained in a set of members.

The automatic creation of imperfections or imperfect systems is possible with the add-on modules RSIMP und RF-IMP.
