The mono-axial shake-table enables the dynamic testing of buildings and large structures weighing up to 140 tonnes, and can reproduce real or generated seismic events. It features a platform measuring 5.6 m x 7.0 m and displacement, velocity and acceleration performances of ±500 mm, 2,000 mm/s and 6.0 g (without specimen) or 1.8 g (with a 60-tonne specimen), respectively. The system relies on a hydraulic system designed to guarantee high performance. This system is characterised by a constant flow rate of 1360 l/min, supplied by eight pumps, and an additional flow rate, if necessary, supplied by five accumulator units.
The table has a cellular steel structure with high rigidity and low mass characteristics, which are compatible with the stresses generated by structural tests. It slides on hydrostatically supported guides to ensure minimum friction.
