000011808 520__ $$2eng$$aA new shaking table called "BRI Large Stroke Shaking Table" was developed in 2006 in the Building Research Institute. The shaking table is driven by wire connected with dynamic actuator and its displacement is increased by 6 sets of pulleys and is 13 times of actuator’s deformation, theoretically. Dynamic range of the table is 2.5 m and is enough to estimate the deformation of 50th floor of high-rise buildings. Performance test of the shaking table was performed on March 2006 by loading 6 periods of sine waves. By these loadings, unexpected vibration around 1.8 Hz were observed. Therefore, analytical model study was performed and it was estimated that unexpected vibration might be caused by telescopic motion of wire. Then, parametric case study was performed and designed oil damper was installed in the shaking table in July 2007. Performance test for damper installed shaking table was performed in July 2007. The unexpected vibration around 1.8 Hz was eliminated by the damper and the shaking table has been ready to perform long period shaking test.
