Seismic protection mageba seismic protection devices – for reliable preservation of structures Hospital Leoben, Austria RESTON®SA Shock Absorber durable, safe, reliable

Seismic protection Characteristics & dimensions Principle mageba RESTON®SA shock absorbers are velocity dependent devices, consisting primarily of a piston, a piston rod and a cylinder pipe. They allow free movements of a structure during service conditions, but provide displacement control and dissipate energy during sudden movements caused by events such as earthquakes, exceptional traffic or high wind forces. The resistance force depends on the flow of a viscous fluid that passes from one chamber of the cylinder pipe into the other. The fluid is squeezed through small holes in the piston whose...

Seismic protection Properties & benefits Mode of operation Corrosion protection The behaviour of RESTON®SA shock absorbers is governed by the following constitutive law: mageba proposes standard corrosion protection systems according to EN ISO 12944, with corrosivity category depending on location, environmental conditions and the required degree of protection. F = C·vα Where: F: Maximum force [kN] C: Damping constant [kN/(m/s)α] v: Velocity [m/s] α: Damping exponent [-] Materials The following materials are used by mageba for the production of RESTON®SA devices: • Main outer steel parts such...
