Seismic stressors

with one-dimensional motion,
two-dimensional and three-dimensional motion.

We have filed two patents concerning para seismic stressors that differ from each other in their operating principle.

Applied to an element to be tested, both produce stresses on it similar to seismic shocks.

The stressor, relating to the first filed patent, essentially produces one-onedimensional harmonic stress.

A wide range of adjustments allows you to apply specific stresses required for different tests to the element to be tested.

The stressor relating to the second patent produces stresses, even of considerable complexity, deriving from the composition of one-dimensional, two-dimensional and three-dimensional movements.

The seismic waves that can hit an object bound to the ground, for example a building, can have considerably different characteristics, which depend on the magnitude of the earthquake, the depth of the epicenter, the distance from the epicenter from the building, the characteristics of the ground that the waves go through, from the consistency of the ground on which the building stands.

The stressor has many adjustments that allow to produce a very wide range of stresses and powers.

It can be applied to seismic test platforms and can also be directly applied to elements to be tested in situ.

The effects of seismic shaking, as well as from seismic waves, depend on the shaken object, its structure, any vulnerable parts of its structure.

Even on site, the stressor can test a structure, for example a building, or its parts for preventive purposes to evaluate its anti-seismic resistance or to evaluate its integrity following seismic events.
