I would like to get references regarding "Modal Participating Mass Ratios", to get better understanding.
I am using Etabs program, response spectrum with Ritz vector, references are very limited in Etabs.
Thanks for your help.

Without going into a long explanation behind the modal participation, you can find what your looking for in the following texts:

Dynamics of Structures: Applications to Earthquake Engineering, Anil Chopra

Structural Dynamics: An introduction to computer methods, by Craig.
