Modal Damping in SAP2000

[easap]

Hi Guys

I have a problem with constant modal damping in SAP2000. It doesn't seem to have an effect on the response when I change the damping, even if I set it to 0,99..

Has anyone encountered this problem? I cannot figure out what is wrong..

Thanks,

Are your periods/frequency validated ?

Actually, I don't experience the problem any longer. Don't know what I was doing wrong earlier.
Anyway, thanks for the reply, I appreciate it
