How to model a seismic linear isolator? Should i use linear spring?
Hello,
it mainly depends on type of seismic isolator. If damping is provided, you can use dashpot (see https://www.nextfem.it/it/a-survey-on-non-linear-analysis-in-nextfem-designer-part-1/).
If bilinear behaviour and damping are present, a bilinear spring with dashpot could be used.
