Question:
I divided a member by several nodes. When applying the imperfections, each partial member is now assigned its own imperfection.
How can I define an imperfection over all partial members?
Answer:
If a member consists of several partial members, it is necessary to specify the objects to which the imperfection should refer when defining the imperfection. You have the following options to do this:
Members
The imperfection has an influence on one member or independently on several members.
List of Members
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 covere 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 generation of imperfections or imperfect systems is possible using the add-on modules RSIMP and RF-IMP.
