Test cases conducted in 1G shaking table test. Photo 6 shows the setup of the model pile foundation and the model ground. The model ground was prepared with the dropping method, with a suitable distance from the dropping mouth to the surface of the model ground kept constant during the dropping so that a ground with uniform density can be prepared.
A similitude is derived for the shaking table tests on saturated soilstructurefluid model in 1g gravitational field. The main tool used for deriving the similitude is the basic equations which govern the equilibrium and the mass balance of soil skeleton, pore water, pile and sheet pile structures, and external waters such as sea.
A straincontrolled model box with flexible walls was used by Yegian et al. 2006 Yegian et al. , 2007. Laminar box tests have been widely used in both 1g shaking table and centrifuge tests to
pioneered small scale and fullscale shaking table tests on reinforced soil walls of metallic reinforcement. Sakaguchi 1996 carried out shaking table tests on a The laminar box used for the tests is rectangular in cross Base acceleration was kept as 0.1g, 0.15g and 0.2g in different tests. Frequency is varied from 1 Hz to 3 Hz. The

Applicability of rigid block based approaches in predicting sandy slope displacements by 1g shaking table tests Nine sandy slope models are constructed and thirtysix dynamic tests are performed by shaking table. The model slope, rigid box with a Plexiglas side and a shaking table device in the SUT earthquake engineering laboratory are
Process under 1G Shaking Table Test . C. H. Chen. 1, C. H. Chen 2, T. S. Ueng 3 and Y. Y. Ko 4. ABSTRACT . In order to quantify the relation of reduction of soil stiffness and excess pore water pressure during liquefaction, the test data of a series of shaking table tests on model pile in saturated sand using a
The shaking table test device used in the present study is shown in Fig. has the maximum payload, acceleration and displacement of 16 kN, 9.8 ms 2 and 0.05 m, respectively. The dimensions of the shaking table shear box are 1.2 m in length, 1.0 m in width and 0.8 m in order to prepare a uniform model ground with a prescribed density, a sanddropping device, placed on the updown
shaking table study of slopes. Seed and Clough 1963 also used shaking table tests to study the earthquake resistance of sloping core dams. Wartman et al. 2003, 2001 conducted a small scale shaking table test to simulate slope behavior under a 1g gravity field. Lin and Wang 2006 used a largescale shaking table test model on sandy slope

The model tests can be divided into two categories, namely, those performed under gravitational field of earth generally called shaking table tests or 1g tests and those performed under higher gravitational field centrifuge tests or multig tests. Both shaking table and centrifuge model tests have certain advantages and limitations.
for carrying out the seismic model test in 1g shaking table or augmented gravity field, Ng geotechnical centrifuge experiments with N time earths gravity are covered. As a result, the laminar shear box is to be found the most common container due to the simplicity of design and modeling and also the accuracy of large strain modeling problem.
Laminar box tests have been widely used in both 1g shaking table and centrifuge tests to study liquefaction of sand owing to earthquake Ling et al., 2003Kagawa et al., 2004Elgamal et al., 2005
