    Abstract
  • Isolation is viewed as one of the most promising technologies to protect buildings from strong earthquakes. The application of electromagnetic levitation techniques for isolation of building structures is a frontier research field in structure engineering. Compared to conventional rubber isolation bearings, an electromagnetic levitation device has an active control capability for both vertical and horizontal isolation of the structures. However, the research on this topic is scarce. Herein, the background and basic concepts of electromagnetic levitation isolation technology is introduced with a focus on the research progress and current development of two electromagnetic levitation isolation systems, namely permanent magnet-electromagnet and armature-electromagnet. Furthermore, some key issues that remain to be addressed in the practical application of electromagnetic levitation isolation are listed. In addition, some suggestions are provided for future research on isolation of building structures based on electromagnetic levitation techniques.
