MECHANICAL PROPERTIES OF SEISMIC ISOLATION SYSTEM WITH FIBER REINFORCED BEARING IN STRIP TYPE

摘要

This paper describes an experimental and theoretical study of the feasibility of using fiber reionforced to produce lightweight low-cost elastomeric isolator. The fiber in the fiber-reinforced isolator, in contract to the steel in the conventional isolator is assumed to be flexible in extension. Several examples of isolators in the form of long thrips were fabricated and tested. The theoretical analysis and test results suggest that it is possible to produce the fiber-reinforced strip isolator that matches the behavior of a steel- reinforced isolator. The fiber-reinforced isolator is significantly lighter and can be made by a much less labor-intensive manufactiring process.
