To examine the performance of furniture in the top stories of high-rise buildings particularly under long-period ground motions, a full-scale shaking table test was conducted in E-defense. A mass-and-rubber system was designed to overcome the limitation of the shaking table. A five-story specimen with large stiffness was set on the rubber-and-mass system. It enables that different stories' responses are same and a lot of furniture experiments are carried out simultaneously. The waves generated from the inverse dynamic compensation were taken as inputs. The test results show that the large responses at the top stories can be reproduced reasonably. Through the shaking table test, physical data of furniture in high-rise buildings under long-period ground motions were obtained.
