Multi-spherical sliding bearings offer several advantages over traditional seismic isolation systems, both in terms of system performance and economy. These bearings are completely passive devices, yet exhibit adaptive stiffness and adaptive damping. This is a result of their unique internal construction, which consists of multiple surfaces upon which sliding can take place. As the combinations of surfaces upon which sliding is occurring change, the stiffness and effective friction change accordingly. Furthermore, since the sliding displacements are shared among multiple surfaces, multi-spherical sliding bearings can be manufactured much more compactly than traditional bearings, providing substantial economic savings. Often, advancements in performance come at the expense of simplicity, reliability and longevity. However, the double and triple Friction Pendulum (FP) bearings investigated in this study are just basic adaptations of the original Friction Pendulum bearing, one of the most widely implemented seismic isolation systems.a€œSAP2000: Static and Dynamic Finite Element Analysis of Structures (Version 11.0.2) Analysis Reference Manuala€, Computers and ... a€œSAP2000 Software Verification Examples: Version 11a€, Computers and Structures, Inc., Berkeley, CA, USA.
