Question:
Does RF-/DYNAM Pro consider elastic supports (nodal and line supports with elastic spring constant) and elastic surface supports?

Answer:
Yes, all supports with a spring constant are considered in the RF-/DYNAM Pro add-on module. In detail, this means that the elastic supports are considered in the following areas:

Determination of natural vibration
Time history analysis of time diagrams
Response spectrum analysis ("Forced Vibrations" and "Equivalent Loads")

The attached example clearly shows how the mode shapes of a member change when an elastic nodal support is added.
