Tri-axial shake table tests were performed at LNEC to investigate the response of the Test Building. The shake table is characterized by a dimension of 5.60 m × 4.60 m, extensible to 5.60 × 6.20 m. The excitation frequencies can range from 0 to 40 Hz and the maximum specimen payload capacity corresponds to 400 kN, which was reached in this case.
Capacity of a shaking table is in the range between 0.5 tons per hour and approx. 1.5–2 tons per hour depending on the particle size processed. Therefore, it is usually a standard in the industry to install tens of shaking tables in series or parallel in order to process excessive tonnages, especially in chromite processing.

In this research, 1 g shake table experiments were conducted to evaluate the effects of boundary conditions on the responses of a 3 × 3 pile group to liquefaction-induced lateral spreading.
For some twenty years, Quanser Shake Tables are helping civil engineering students grasp complex concepts of structural dynamics and earthquake engineering more quickly and thoroughly. Engaging, hands-on experiments allow them to leap past dry theory and 'experience' an earthquake in safety of the lab. Inspired by Dr. Shirley Dyke, the driving force …
The shaking table is an important test equipment for studying the seismic resistance of structures. Its vibration form has developed from single-axis single-degree-of-freedom to three-direction six-degree-of-freedom, and the control algorithm has undergone a development process from traditional control to intelligent algorithm control. Investigation and …
The first shake table was built in 1968, and since then, a considerable number of shake table and table array devices have been constructed worldwide. The most famous one is E-Defense in Japan's National Research Institute for Earth Science and Disaster Prevention which is also the largest one in the world.
Working Principle. Shaking Table is comprised of head motion, deck, feed and water box and base. The deck is mounted on the supporting base that allows the table to slide along the long axis of the table. A acrylic feed distributing box with hopped and a long water box are attached to the iron of the deck, giving a very even distribution of feed and water.
