Comments/Conclusions

 

The critical perturbations at 15h10 (red) represent an unacceptable environment for the micro balance.

 

The critical permanent perturbations over a 15 minutes time period show amplitudes over 2000m/s.

 

As expected by experience, values over about 2000m/s get critical.

Such perturbations have to be analyzed and to be reduced or removed by damping, geotechnical or other
organisational measures.

 

 

Red arrows: low frequency strong permanent shaking perturbation (on the granite table).

 

Green arrows: single delta peaks perturbation (hit on the granite table in the z-direction)
