The dynamic testing apparatus for medium to large dimension seismic devices is one of the main facilities of SisLab. The complete testing package (software, hardware and instrumentation) enables testing at extremely high performance levels. The apparatus allows technical approval testing of various seismic devices (elastomeric isolators, friction sliders, friction pendulum isolators, displacement dependant devices and velocity dependant devices) in accordance with current standardization.
The testing machine has a maximum stroke of ± 500 mm, a maximum horizontal load of ± 1000 kN and a maximum vertical load of 8000 kN. The testing machine is serviced by hydraulic system capable of providing flows of up to 1800 litre/min. The apparatus is capable of performing tests on single devices with dimensions of up to 1.7 m long, 1.5 m wide and 0.6 m deep.
