Shaking Table Research Facilitiies
There are several different experimental techniques that can be used to test the response of structures to simulated earthquake loading, one of which is the use of a shaking table. An earthquake shaking table is a device for shaking large structural models and components with a wide range of simulated ground motions, including reproductions of recorded earthquakes. It typically consists of a large, rectangular platform that is driven in up to six degrees of freedom (DOF) by servo-hydraulic or other types of actuators. Test specimens are fixed to the platform and shaken, often to failure, but it should be noted that the control of such systems is not a trivial problem. Using data recorded from transducers it is possible to interpret the dynamic behaviour of the specimen. Shaking tables are used extensively in seismic research, as they provide the means to excite structures in such a way that they are subjected to inertia loads representative of true earthquake ground motions.

A World List of Shaking Tables
Below is an attempt to create a definitive list of shaking tables around the world that are used use for seismic testing. The list is almost certainly not complete and not all the data has been verified by the shaking table owners. If you operate a shaking table please help by correcting and updating and adding to this list.

This list was originally based on information from the following documents: Experimental Facilities for Earthquake Engineering Simulation Worldwide, Directory of International Earthquake Engineering Research Facilitiesand papers by Chowdhury, Duarte , Kamimura and Nakashima and EERI.

Notes: This list is restricted to shaking tables bigger than 2m by 2m and with a capacity of more than 4 tonnes (i.e. tables suitable for seismic testing).
