Spring and dashpot

[bassking]

Hello, i'm studiyng the seismic response of a multi span bridge. In my analysis i take great attention to the soil-structures interaction. The simpliest model to study the problem is to substitute the soil under the foundation with a spring and a dashpot. So i have a costant K for the spring and a C for dashpot, can i use zeroLength element for the analysis, maybe using Maxwell material, who take in account stiffness and damping?
