Hello everyone,
I would like to ask how I can calculate the self-weight of specific groups of members that I have defined in my model.
Is there a way to extract or display the self-weight contribution only from selected member groups (GRP)?
Hi,
a group wise activation of the structure self weight is NOT possible.
There is only one workaround: you define a material with gamma = 0.00 and use this material for all elements and cross sections you don’t want to have a self weight.
That’s all you can do.
Okay, thanks. This is what I was doing as well, but I thought there would be a more efficient way.
Perhaps this will help:
In the calculation (ASE etc.), all model elements can be controlled on a group basis (GRP, GRP2), which also allows the dead weight approach to be regulated.
This is used, for example, in construction process calculations, where some groups are activated from a total system, with none activated in group 9 and 2.222 times the weight activated in group 11.
If group-based dead weight is applied (GRP FACD …), DLX/DLY/DLZ is no longer permitted for LC.
Regardless of this, the MSH protocols (with the appropriate output depth) also show the 1.0 fold dead weight of the various element types for each group.
