This report describes the formulation, implementation and validation of multi-spherical sliding bearing models that can be used for response history analysis. When configured to exhibit adaptive behavior, double and triple Friction Pendulum (FP) bearings exhibit hysteretic behavior that is more complex than that exhibited by current seismic isolation devices. The methodologies described in this report are verified by comparing the results obtained from shake-table testing of a quarter-scale, six-story model to those predicted by response history analysis. There is generally good agreement even in cases of extreme response, which attests to the proposed models' robustness and overall validity.
