Pseudo Spectral Acceleration

Pseudo Spectral Acceleration

Pseudo Spectral Acceleration

Can someone explain the concept of pseudo spectral acceleration?
I am somewhat familiar with spectral acceleration; just not familiar with the term 'pseudo'?

RE: Pseudo Spectral Acceleration

I believe, it is the maximum spectral response of a damped single degree freedom system under a given ground acceleration history.

RE: Pseudo Spectral Acceleration

How does that differ from 'spectral acceleration' (i.e. losing the term pseudo)?

RE: Pseudo Spectral Acceleration

The difference between spectral and pseudo spectral acceleration is negligible and most often they are the same thing.
