help for damping in Mdof

Post by natdickstein »

Hi. i have a problem with a mdof building with 40 stories. is there a way to define the damping matrix by the alternative metod of superposition of modal damping present in chopra's book. with the rayleigh damping i can't have for all modes the same damping ratio.
thanks
