From fig.10c, it can be seen that the predominant frequency of the scaled earthquake signal measured on the table is 3.32 hz as opposed to 9.23 hz see fig.10b due to inertia effects and limitations of the actuator and control system used in the shaking table tests as discussed above in the methodology.Get Price List
1.Introduction.Having an accurate understanding of phenomena such as seismic response of soil deposits and soil-structure interaction continues to be one of the favorite topics in geotechnical earthquake engineering.To this aim, the scaled shaking table test is commonly carried out because of its ability to provide a controlled environment and to permit economic parametric studies.
Abstract.Liquefaction is one of the most destructive natural hazards that cause damage to engineering structures during an earthquake.This study aims to examine the effect of rubber and gravel drainage columns on the reduction of liquefaction potential of saturated sandy soils using a shaking table.

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.
A series of shaking table tests on a 112-scale model using scaled taftn21e earthquake records were conducted to investigate the seismic performance of a 17-storey high-rise reinforced concrete structure with a high degree of torsional eccentricity and soft-storey irregularities in the bottom two storeys.
