Viscous dissipators are used to dissipate a big part of the vibration energy suffered by a structure when an earthquake or another abrupt movement happens. This way, they protect the main structural elements, which provide additional damping to the structural system.
RESTON-SA shock absorbers by MAGEBA are hydrodynamic devices sensitive to speed. They have a piston, a piston rod and a cylindric tube. The resistance of these shock absorbers depends on the flow of viscous material that goes to other cavity of the cylindric tube. This fluid travels through holes in the piston. The size of these holes determines the performance of the shock absorber.
This viscous shock absorbers guarantee a normal performance of the structure in common conditions, while dissipate energy and limit sifting when abrupt movements occur (earthquakes, extreme traffic or strong wind).
RESTON-SA shock absorbers dissipate the energy generated in exceptional situations. This way, the impact on the structure is reduced. Thanks to this performance, we are able to optimize the design of the structure and avoid other conventional reinforcements which won’t be used over the useful life of the asset. Thanks to RESTON-SA, we get a 30% additional damping and charges over structural elements are reduced.
