Outline of Final Research Achievements

In this study, in order to investigate the shear behavior and shear properties of Rubber Bearings (RB) subjected to tensile force, cyclic loading tests using 7 test specimens of RB were conducted. To evaluate the shear properties of RB, here in, the tests varied with axial stress were carried out. It was found that the rubber bearing could be deformed largely when it subjected to a tensile-shear loading by experiments and analyses. It is also expected that the results of this study are utilized for the estimation of seismic damage mechanism in the 2016 Kumamoto earthquake.
