The multiple shaking table facilities are the prospective direction in the development of earthquake simulation shaking tables in engineering structures. In recent years, the new multiple shake-table facility systems were constructed in some famous universities and research institute in China. They provided a powerful testing platform for seismic engineering theoretical study and experimental research. In this paper, the state-of- the-art of the multiple shake-table facilities were briefly summarized, and the application of the multiple shaketables testing, especially in building engineering, large-span bridge engineering, energy lifeline engineering and electromeehanieal equipments, were introduced. New developments of model similarity relationships, and experimental technology of the muhiple shake-tables were also illustrated. New methodology and theory in utilizing the system will be brought out and improved in the near future. It is expected that the paper will refer to the seismic study and application of the multiple shake-table facilities.
