One of two shaking frequencies was chosen for each test, 25 Hz represented an earthquake scaled by laws of similitude developed by Iai [29] for 1 g shaking table tests to a 1/20th of the prototype size, whilst 10 Hz represented an earthquake with ground displacement larger than that of the average grain size of the soil 0.18 mm.
Small scale rubberized concrete columns were fabricated and tested under free vibration to identify damping ratios, and on seismic shaking table tests to investigate the structural responses to earthquake ground motion. Increase of damping ratio and reduction of seismic response of concrete structures was reported.
Shaking table tests are able to produce nearly realistic prototype conditions, giving important insight into critical issues such as collapse mechanisms, component …

The "Rota Shake Table" can move in 6 degrees of freedom (6 DOF) with 8 servo-hydraulic cylinders. This means the system can perform translational and angular movements in the X, Y, and Z axes separately or in combination. Sensitive seismic loading can be achieved with these movable tables, providing a wide opportunity to evaluate their behavior ...

Soil–pile interface conditions during seismic events could cause a severe impact on the response of deep foundations which is not fully addressed in the previous contributions. To answer some practical questions, a series of small-scale shaking table model tests were first performed to study the seismic response of fixed-head single piles …

Experimental results are reported and recommendations on the use of these adaptive control techniques are discussed.
The Shake Table II consists of a top stage driven by a powerful motor that allows it to achieve an acceleration of 2.5 g when loaded with a 7.5 kg mass. The stage has a total travel of 15.2 cm and rides on two ground-hardened metal shafts using linear bearings, which allows for smooth linear motion with low path deflection.
The shaking table is an old and reliable technique widely used in the mining and recycling industry. The shaking table, also known as gravity separation, has different relative movements against …

The two large‐scale shaking table tests of tall buildings on soft soils in pile group foundations are performed to capture the effect of the seismic pile‐soil‐structure interaction (PSSI) on the dynamic responses of the pile, soil, and structure. The two different model conditions are observed, including a fixed‐base structure and a structure …
Operators can preprogram desired shaking patterns, which, in the case of simulated seismicity, are often taken from records of actual ground accelerations in past earthquakes. Numerous shake table facilities exist worldwide today, although most are relatively small, measuring only a few meters or less on a side.
The objective of this study is to validate the uni-axial sinusoidal performances curves and to assess the accuracy and fidelity in signal reproduction using the advanced adaptive …
A Gold Shaking Table are basically low-capacity machines used as last step in the gold upgrading process. The shaking table is a thin film, shear flow process equipment, that separates particle grains of its feed material based on the differences in their specific gravity, density, size and shape. Mineral rich particles, from light to heavy …
The similitude laws regarding stress and strain cannot be satisfied completely in small shake table tests since higher gravitational stresses cannot be produced.
