Abstract

Shaking tables have limitations for the maximum displacement, velocity and acceleration. This paper proposes a shaking table test technique to expand the reproducible high frequency range of the table and realize large acceleration. This technique uses two systems: one is the pounding system and the other the high-frequency system. The pounding system hits the high-frequency system first and a free vibration occurs on the high-frequency system. Repeating the pounding, the free vibration of the high-frequency system continues and large amplitudes can also be achieved. To validate this technique, a shaking table test was conducted, and the test results show the efficiencies of the proposed technique.
