“…An FPB is composed of two curved sliding surfaces providing horizontal restoring force and a hemispherical slider between the two sliding surfaces (Peng et al, 2022). The FPB base isolation systems are widely applied to solve the difficulties in isolating large displacements using LRB (Drozdov et al, 2007;Kravchuk et al, 2008;Chen and Xiong, 2022). For example, the world's largest FPB with a 4 m diameter was installed on the Benicia Martinez Bridge in United States (Kravchuk et al, 2008).…”

In this paper, the development of non-linear building isolation systems is overviewed. The study summarizes commonly used linear building isolation systems in two categories, which are building base isolation systems and building inter-storey isolation systems. Typical isolators including Lead-Rubber Bearings Friction Pendulum Bearings inter-storey viscous damper and Tuned Mass Damper are reviewed. The analysis and design of linear building isolation systems are also reported. After that, non-linear building isolation systems are introduced from two aspects based on their dynamic characteristics. They are (i) non-linear stiffness isolators including Quasi-Zero Stiffness isolators and Non-linear Energy Sink and (ii) non-linear damping isolators including power-law viscous dampers and magnetorheological dampers. Practical implementations of these non-linear isolators are introduced. Finally, the analysis and design of non-linear building isolation systems are discussed. Traditional equivalent linearization approaches and advanced non-linear frequency design approaches are introduced. The promising applications of the non-linear frequency design approaches to building isolation systems are also demonstrated in this review paper.

The sea platforms Lun A and PA B of the Sakhalin 2 project erected off the northwestern coast of Sakhalin have been designed and constructed taking into account the severe regional seismicity in which they are used. Their design, which incorporates an effective frictional pendulum bearing (FPBs are capable of running damage and failure free when exposed to loads created by earthquakes, which occur once every 200 years, and should stay undamaged in the case of a rare earthquake, which occurs once every 2000 years [1][2][3]. When the Arkutun Dagi deposit was put to use, the seismic reliability of oil producing Sakhalin 2 project was designed for use on the previously tested platforms at the Lun and Piltun Astokh deposits. The Sakhalin 2 project was seismically protected and have been successfully and safely used since 2007. These works used experimental calculation techniques to estimate the life of the seismic insulating pendulum sliding bearing in order to determine its wear rate. The dependences of determining the wear rate are presented in summarized variables and the coefficient of friction and temperature assessments to establish the temperature condition of the FPB [4,6].
