Seismic protection mageba seismic protection devices – for reliable preservation of structures Highway A3, Mels, Switzerland RESTON®PSD Preloaded Spring Damper dissipating, resisting, recentering

Seismic protection Characteristics & dimensions Principle mageba RESTON®PSD preloaded spring dampers are designed to perform the following functions: RESTON®PSD preloaded spring dampers can dissipate over 30 % of the introduced energy due to a dynamic event. • For general loads due to traffic, creep, shrinkage and thermal variations, the RESTON®PSD devices act as fixed points of the structure and do not allow any movements. This allows the structures to be protected at a lower cost as compared to conventional strengthening methods. • In a seismic event, the RESTON®PSD devices allow the structure...

Seismic protection Properties & benefits Mode of operation Corrosion protection The behaviour of RESTON®PSD preloaded spring dampers 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 = F0 + K × x + C × vα Where: F: Maximum force [kN] F0: Preloaded force [kN] K: Stiffness [kN/m] x: Stroke [m] C: Damping constant [kN/(m/s)α] v: Velocity [m/s] α: Damping exponent [-] Materials The following materials are used...
