pseudo-static methods (Bathurst and Hatami 1998). Shaking table experiments on reduced-scale models are the most practical approach to gain further qualitative and quantitative understanding of the behavior of GRS walls under seismic loading. A disadvantage of a reduced-scale test is that the response of the model may differ from prototype-scale

Shaking table testing of geotechnical models ...

Jun 30, 2015  Shaking tables provide one means of obtaining data from physical models of geotechnical systems under simulated earthquake loading. While there may be challenges in ensuring exact scaling of all aspects of a geotechnical system between prototype and model, the large size of the shaking table models does give a good basis for validation of numerical modelling strategies.
