Spring and damper in parallel

[VooDoo]

Hey guys,

I was just wanting to know, if there is a special way to add a damper in spring in parallel (as per the image below).

i know that springs in parallel is; 1/k(total) = 1/k1 + 1/k2...

Put the spring in a viscous medium.
Actually any real spring is a little bit like that.
