Shaking Table Model Experiments


Carefully controlled shaking-table model experiments will help in the calibration/verification of theoretical methods, and will offer additional insight into the nature of some complicated mechanics. Most of these experiments will be conducted will be conducted in the recently developed Laboratory for Experimental Simulation of Seismic Response of Soil-Structure Systems, the dynamic branch of the Laboratory of Soil Mechanics (LSM). The Lab is equipped with a modern 3-D shaking table, capable of shaking specimens of up to 2.5 tons, at accelerations of up to 1.6 g.


Task 5.1. : Upgrading of Infrastructure
Task 5.2 : Shaking Table Testing

To gain insight into scale effects, a smaller number of model tests will be performed in the larger shaking table (10 ton, 2 g capacity, six degrees of freedom) of the co-operating Laboratory of Earthquake Engineering (LEE) of our School. When finally the methodology will have been developed, a small number of high quality tests will be conducted for verification purposes:

  • – in one of the top European centrifuge facilities
  • – on the huge shaking table facility of the Japanese E–Defense.

Careful planning of these tests will ensure the efficiency of this activity, which will increase the credibility of our research.

Upgrading the facilities, especially equipping them with (additional) high–tech miniature sensor devices, advanced devices for measuring in-situ soil characteristics (e.g. miniature CPT, lab-vane, bender elements, and so on) will be the first but long–term task of this work package.
