Earthquake shaking table Wikipedia

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 with a wide range of simulated ground motionsDespite the advantages of testing models with 1g shaking table, the results may somehow be different from the behaviour of the conceived prototype structures (Munoz et al, 2012, Tatsuoka et al, 2012) due to (i) pressure level and (ii) particle size effects, ie effects of the ratio of particle size to model sizeNonetheless, GRS RW model tests are likely to be suitable for stabilityDeformation and localisation behaviours of reinforced
