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...
