Earthquake response - Single degree of freedom elevated mass

Earthquake response - Single degree of freedom elevated mass

Hello

Don't know if this is in the right forum but I'm looking for some tips on analysis of the earthquake reponse of an elevated mass.  I have the mass, the natural frequency and the damping coefficient.  I am also told the ground acceleration due to the earthquake can be approximated by the constant spectrum So=0.0075m2/s3.

I am struggling as to how to use this in an attempt to find the frequency response function of the mass and the mean square response of displacement.

Any pointers??

Thanks

Hmmmm I think earthquake response are typically in PSD or g^2/hz, which in turn is Random Vibration.  I'm not sure what the So=m2/s3 is...

Thanks guys

How do I go about using the response to find the response function of an object?

RE: Earthquake response - Single degree of freedom elevated mass

Analytical or numerical?

Perhaps it's time to re-read the course text, or find a different one that may be more comprehensible.
