Shock Response Spectrum (SRS)

Shock Response Spectrum (SRS)

(OP)
I would appreciate some help regarding analysis of SRS in MSC/NASTRAN. I have generated a SRS from a (close to) a half sine shock in the time domain, and want to use this as an input in MSC/NASTRAN sol 103. What about the damping? I alredy defined a damping when generated the SRS (The SRS was not generated in NASTRAN). Should I define a damping again when running the SRS sol 103 analysis?
'
Any useful hints would be appreciated.
Thanks

RE: Shock Response Spectrum (SRS)

your SRS function is associated to a damping value - probably the one you already defined.
Now you also can define modal damping function correspondent to your system.
