    Shaking table test is an experimental technique used in earthquake engineering to simulate ground motions. Since the emergence of shaking tables in the 1920s, large number of earthquake model tests have been performed. Shaking table tests have been considered as 1g modelling, in which the gravity acceleration of the model
