This paper presents an experimental research aimed at developing a new rubber-based seismic isolator called ‘'Ball Rubber Bearing (BRB). The BRB is composed of a conventional steel-reinforced multi-layered rubber bearing with its central hole filled with small diameter steel balls that are used to provide energy dissipation capacity through friction. in this study, the shear test was performed to compare the NRB & LRB & BRB. bearing shear tests were carried out as per ISO22762 for seismic isolation design standard. A test results showed that EDC & effective stiffness of the BRB is lower than LRB.
