The accuracy of a series spring model to predict the peak displacement and displacement history of Triple Pendulum (TP) bearings in a strongly shaken, full-scale building is evaluated in this paper. The series spring model was implemented as a self-contained three-dimensional TP bearing element in OpenSees and is now available for general use. The TP bearing element contains the option for constant friction or a generalized friction model that accounts for the effect of instantaneous velocity and compression load on the friction coefficient. Comparison between numerical simulation and experimental data of a five-story steel moment frame building shows that the peak displacement of isolation system can generally be predicted with confidence using a constant friction coefficient model. The friction coefficient model accounting for the effect of axial load and velocity leads to minor improvement over the constant friction coefficient models in some cases.
