Fiber-reinforced elastomeric isolators: A review

Van Engelen, Niel C.

Abstract The concept of seismic isolation is well established. Provisions for seismic isolation are gradually being included in building and design codes around the world. Consequently, the quantity of base isolated structures continues to grow globally with favorable performance observed after every significant seismic event. The growth in seismic isolation technology has led to the development of numerous innovative and unique base isolation devices. Although many different types of devices exist, most can be classified as either an elastomeric or sliding isolator. Within the elastomeric classification, steel-reinforced elastomeric isolators are the most common. Fiber-reinforced elastomeric isolators (FREIs) have been proposed as a type of reinforced elastomeric isolators that have distinct performance characteristics. The original intent of FREIs centered on developing a low-cost device appropriate for wide-spread application, particularly in developing countries where the devastation of earthquakes is often more severe. For this reason, the concept has gained significant attention within the research community. This review summarizes the development and current state-of-knowledge of FREIs.

Highlights • This paper is the first comprehensive literature review on fiber-reinforced elastomeric isolators (FREIs). • The reference list is exhaustive for English language peer-reviewed journal publications. • The impetus for the device and development is explained. • FREIs are differentiated from conventional steel-reinforced elastomeric isolators. • All important areas of development and research activity are discussed.
