Experimental Study of a reduced scale model seismically base isolated with Rubber-Layer Roller Bearings (RLRB)

Abstract

The main purpose of the research reported here is to investigate the behavior of Rubber-Layer Roller Bearings (RLRB) used to base isolate a low-rise structure during horizontal ground motions. The isolation system consits of high damping natural rubber pads and steel balls. In order to study the behavior of this kind of base isolation device, a theoretical approach of the problem has been conducted, followed and completed by a series of experimental shaking table tests performed on a scaled model of the entire structure.
