    Hi Arul,

     

    Do you have any reference for the assumption you are talking about?

    Arul,

     

    I think modal damping depends on the critical damping of the structure and damping coefficient and it may vary from 0.01 to ~0.2

     

    Please refer to any books which deals with modal analysis and modal damping.
