The Friction Pendulum System was introduced in a companion paper, placing the emphasis on an experimental study in bridge seismic isolation. The available analytical techniques are employed herein in the prediction of the response of the tested bridge model. The analytical model accounts for the pier flexibility, pier top rotation and vertical motion effects on the properties of the FPS bearings. Comparison of experimental and analytical responses shows very good agreement. This demonstrates that the behavior of FPS bearings is very well understood to allow for accurate prediction of the response of isolated structures with these bearings.
