March 2, 2021 at 8:40 am #3647 NextFEM AdminKeymaster 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. Author Posts Viewing 2 posts - 1 through 2 (of 2 total) You must be logged in to reply to this topic.
