ULTIMATE DEFORMATION CAPACITY OF LEAD RUBBER BEARING UNDER COMPRESSION

Abstract

This paper presents the experimental results of ultimate deformation capacity and energy dissipation capacity of lead rubber bearings. The lead rubber bearing absorbs the energy in lead plug (circular rod) inserted center. The effect of the interaction of lead plug and laminated rubber bearing has not sufficiently been clarified. Using the two type specimens : test specimen including the lead plug and without lead plug, the ultimate performance of lead rubber bearing is confirmed. Based on the results of compressive shearing tests, the effect of lead plug on the characteristics of lead rubber bearing under the high compressive stress were clarified.
