Numerical and Experimental Analysis of the Load-Carrying Behaviour of Laminated Elastomeric Bearings as Seismic Isolators
Abstract
Depending on the structural form and the strength of the vertical seismic force, a seismicady isolated structure may experience a rocking motion during earthquake, which leads to the uplifting on one side and could cause the tensile force in the isolator bearing. The rubber isolator bearings are known to be capable of carrying a little tensile force but their tension capacity has not been utilized in practice because of the cavitation phenomenon which occurs when the rubber bearing is subjected to a certain degree of tension. Comprehensive research regarding this phenomenon on the rubber bearing is rarely found and therefore the aim of this dissertation is to provide an overview of the mechanism of cavitation phenomenon as well as the consequence of cavitation on the properties of the rubber bearing. For that purpose, different types of elastomeric bearings are analysed numerically and experimentally.
