No, the information regarding the self-weight of the joint is not transferred from the Steel Joints add-on to the structural analysis model.
This means that the user needs to consider the additional weights from the joints as a load in the steel structure model. This applies regardless of whether the Steel Joints add-on is used or not.
The additional weight from joints can be taken into account as a nodal load in the “Self-Weight” load case.
Furthermore, it is possible to consider the weight from steel joints using the self-weight factor in the “Self-Weight” load case. The additional weight from joints is then “distributed” across the entire structure.
When using this procedure, you should not define any other loads—for example, those from grillage or trapezoidal sheeting—in the “Self-Weight” load case, as these loads would then also be increased by the same factor.
