Shock Absorber.

I was reading the notes about the measures to adapt and respond to earthquakes and was thinking about the part which they wrote about designing new infrastructure. A question popped up, how do the shock absorbers actually work? How exactly does the shock absorbers actually 'absorb' the tremours?
I found this on Wikipedia:

Structures
Applied to a structure such as a building or bridge it may be part of a seismic retrofit or as part of new, earthquake resistant construction. In this application it allows yet restrains motion and absorbs resonant energy, which can cause excessive motion and eventual structural failure.

After reading this, I don't really get it. What do they mean by 'yet restrain motion and absorb resonant energy'? They also mentioned that it can cause structural failure, that what is the use of it?

To sum up this whole post, it's about the some questions about the shock absorber.
