Sliding Isolation Systems: Historical Review, Modeling Techniques, and the Contemporary Trends

Abstract

Base isolation techniques have emerged as the most effective seismic damage mitigation strategies. Several types of aseismic devices for base isolation have been invented, studied, and used. Out of several isolation systems, sliding isolation systems are popular due to their operational simplicity and ease of manufacturing. This article discusses the historical development of passive sliding isolation systems, such as pure friction systems, friction pendulum systems, and isolators with other sliding surface geometries. Moreover, multiple surface isolation systems and their behavior as well as the effectiveness of using complementary devices with standalone passive isolation devices are examined. Furthermore, the article explored the various modeling techniques adopted for base-isolated single and multi-degree freedom building structures. Special attention has been given to the techniques available for modeling the complex phenomena of sliding and non-sliding phases of sliding bearings. The discussion is further extended to the development in the contemporary areas of seismic isolation, such as active and hybrid isolation systems. Although a significant amount of research is carried out in the area of active and hybrid isolation systems, the passive sliding isolation system still has not lost its appeal due to its ease of adaptability to the structures.

Seismic Impact on Building Structures: Assessment, Design, and Strengthening

“…They also highlighted the capacity of the multiple active tuned mass damper system with an inerter system in checking structural and environmental fluctuations, which leads to superior robustness and stability. Finally, Avinash et al [14] provide a comprehensive review of sliding isolation systems considering several dimensions of base isolation systems. They incorporated hybrid and active isolation systems, shedding light on passive sliding isolation systems.…”

Theoretical and Experimental Study of Rotational Behaviour of Friction Pendulum Bearings

“…It also means that simple connection elements of FEM software can be used to simulate rotational characteristics of FPB bearing. (2) From Equation (9), the rotational stiffness k α of the FPB can be obtained by Equation (12).…”

“…Friction Pendulum Bearing (FPB) are reputed to be very efficient at reducing the risk of damage and collapse for structures [6][7][8][9][10][11][12].…”

Non-Linear Dynamics of Simple Elastic Systems Undergoing Friction-Ruled Stick–Slip Motions

“…Elastic elements undergoing stick-slip motion in the presence of friction can be found in many physics and engineering systems in a range of length scales from micrometers [1] to kilometers [2]. In the civil engineering field, for instance, various solutions proposed for protecting buildings from earthquakes, e.g., devices for controlling the amplitude of oscillations or isolating buildings from the ground [3][4][5][6][7][8], undergo stick-slip motions. Among the damping devices, a common solution exploits the friction force that develops between elements forced to slide with friction over each other, as in the slotted bolted connection (SBC) [4] represented in Figure 1.…”
