When mass of the structure is represented by Lumped Mass or Concentrated Mass element in finite element analysis, it does not add any stiffness of the structure.
When the structure is subjected to inertial loading, i.e., gravity or acceleration loading, this concentrated mass is converted to weight and act as a force.
When there is no inertial load, only mechanical loads, like force, in a static fea, what this lumped or concentrated mass does.
It does nothing, because mass only comes into play when there is inertial loading.
Thanks for your clarification and valuable input.
