000018522 520__ $$2eng$$aIn the past decade, the friction pendulum system (FPS) has been verified as a reliable seismic resisting. The longer vibration period and the concentration of energy dissipation are the underlying reasons for its effectiveness. However, its application in high-rise buildings is currently restrained by a major concern that the damage of superstructure is mitigated at the expense of excessive bearing deformations. In order to reduce the lateral displacement demand, one possible solution is to supply additional damping. This paper studies the seismic performance of the FPS supplemented by fluid viscous dampers. A design framework is proposed for this new seismic isolation system. Taking a high-rise shear-wall structure for example, the prototype design is also conducted to demonstrate this framework. Based on nonlinear time history analyses, it is found that fluid viscous dampers are able to control bearing deformations within the reasonable capacity. Bearing uplift, induced by the massive overturning moment, is considered in the proposed framework. By optimizing the layout of bearings, the uplift can be avoided in minor and moderate earthquakes. In major earthquakes, although slight uplifts are observed, the overall performance of the new seismic isolation system remains stable.
