Damage to high-tech equipment during earthquakes will cause huge loss in economy. To offer a solution to aforementioned problem, in this study a novel base isolator called the static dynamics interchangeable-ball pendulum system (SDI-BPS) is proposed. This isolation system uses steel balls to support the primary static load when the system is in service and the rubber steel balls to provide damping for controlling the isolator displacement when subjected to ground motions. The efficiency of the proposed isolation system has been proven through a series of full scale shaking table tests in the Center for Research on Earthquake Engineering (NCREE) in Taiwan. The experimental results show that the acceleration responses of motion sensitive equipment isolated with SDI-BPS isolators were reduced by more than 80%. It is concluded that the static dynamics interchangeable-ball pendulum system is a promising isolation system for protecting critical equipment from earthquake damage.
