The shaking table they created is the same one operated by PEER today and is still the largest multidirectional shaking table in the United States and among the most sophisticated in the world. Many of the design features originated in Berkeley, were later adopted for shaking tables in Japan, Mexico, Peru, and Yugoslavia.
FFMCS has been developed as part of a joint Japan-UK initiative, motivated by prior testing of shaking-tables located in both Japan and Europe. This paper describes the dynamic modelling of a typical shaking-table, in order to emphasize the key features required of its controller.

This research was undertaken to explore the interaction behavior of soil-pile systems subjected to static and dynamic lateral loads. The principal objective of the study was to assess the applicability and accuracy of one of the prominent methods of analysis by comparing the predicted responses with the measured responses.
Shaking Table Testing 8 log 2 m e mn a a h n (7) (4) Shaking Table Test A simple test using a small shaking table will be performed to determine the dynamic properties of the specimen. The table is driven harmonically with the specified frequency. The frequency of the harmonic wave can be controlled step by step and accelerations at the base
Shaking table testing is a common experimental method in earthquake engineering for performance assessment of structures subjected to dynamic excitations. As most shaking tables are driven by servo hydraulic actuators to meet the potentially significant force stroke demand, the review is restricted to hydraulic shaking tables.
There are several different experimental techniques that can be used to test the response of structures and soil or rock slopes to verify their seismic performance, one of which is the use of an earthquake shaking table (a shaking table, or simply shake table). This is a device for shaking scaled slopes, structural models or building components ...
Shaker Tables for Vibration Testing and Calibration Shaker Tables for Vibration Testing and Calibration. In the world of vibration testing, the words "shaker table" or "vibration table" can have many different meanings. Shaker tables are used to perform various types of testing, from general vibration testing of components to vibration ...
1991). Accordingly, a number of shaking table tests have been performed on various models of soil-pile-structure systems to understand the ... Shimizu Corporation, Tokyo. Fig.1 ... Table 1 Specifications of shaking table test Radius of rotation Size of shaking table Centrifuge acceleration
Electro-hydraulic shaking tables are widely used for vibration testing where high force and displacement amplitudes are required. In particular, they are a vital tool in seismic testing, enabling the development of buildings and other structures which are earthquake resistant.
In this study, a new real-time substructuring technique for the shaking table test was proposed. The proposed substructuring technique adopts the upper part of the whole structure as the experimental substructure, which corresponds to a physical test model. The lower part is modeled numerically.
To study the seismic performance of hollow reinforced concrete piers under dynamic loads, nine hollow pier specimens with different stirrup ratios, reinforcement ratios, and axial compression ratios are designed and manufactured. The El Centro wave, Taft wave, and artificial Lanzhou wave are selected as seismic excitation for the shaking table test. The effects of the reinforcement ratio ...
It is also equipped with E-Spider, the world's most advanced large-stroke shaking table, which is capable of simulating the seismic response of structures during a long-period earthquake. Shimizu is using these systems to focus on research and development on both the hard and soft aspects of earthquake disaster prevention and mitigation technology.
In this paper, the Minimal Control Synthesis (MCS) is applied to a shaking table-test control. The MCS has been implemented in the controller design for the experiments of the small-scale and the medium-scale shaking table and proved to be effective for enhancing shaking table control by the experiments. ...
