PROPOSAL OF DAMPER WITH LARGE DEFORMATION CAPACITY USING HIGH DAMPING RUBBER BEARING AND DYNAMIC PERFORMANCE TEST UNDER ALMOST ZERO COMPRESSIVE STRESS

Abstract

In this paper, we propose a damper with large deformation capacity in two directions using high damping rubber bearings (HDRs) as damping component. Damper unit and horizontal force transmission unit is joined by bearing-type joint, and the vertical force does not act on HDRs. Therefore, HDRs only support the weight of damper unit and deform bi-directional under almost zero compressive stress. We confirmed that the proposed damper act with intended by dynamic loading test using scaled specimen.
