Product catalog summary
Seismic Protection Overview
mageba's RESTON®PENDULUM Curved Surface Sliders are designed to protect structures from seismic activity by utilizing a pendulum principle. These devices allow horizontal displacement, shifting the natural period of the structure to prevent resonance during earthquakes. The system's effectiveness is primarily determined by the radius of curvature and the coefficient of friction.

Key Properties
  • Transmit vertical forces and allow horizontal displacements under normal conditions.
  • Provide lateral flexibility during earthquakes through sliding elements.
  • Energy dissipation via dynamic friction between sliding surfaces.
  • Re-centering function through gravity and device geometry.

Types of RESTON®PENDULUM
  • Mono (PM): Features a primary curved sliding surface and a steel element with ROBO®SLIDE for sliding, designed for specific maximum displacements.
  • Duplo (PD): Includes two sliding surfaces for higher displacements and rotational capacity, suitable for bridges.

Materials and Dimensions
  • Steel parts made from S355, ROBO®SLIDE material, silicone grease, hard chrome coating, and stainless steel sliding plates.
  • Dimensions vary based on vertical load and maximum design displacement, with specific values provided for both Mono and Duplo types.

Benefits
  • Reduces dynamic impact, increases seismic safety, and allows for slender structures.
  • High load-bearing capabilities and re-centering features.
  • Adaptable for new and existing structures, with minimal maintenance required.

Corrosion Protection
Standard systems according to EN ISO 12944, with options for other standards upon request.

Quality and Support
  • Certified quality systems and CE certification ensure high standards.
  • Testing available in-house and with third-party institutes.
  • Installation supervision and maintenance manuals provided.

Customer Support
mageba offers consulting for optimal seismic solutions and provides extensive product information and support through their website.

Seismic protection Characteristics & types Principle mageba RESTON®PENDULUM curved surface sliders are based on the working principle of a pendulum. They allow the horizontal displacement of structure, providing the required shift in the natural period of the structure. Once activated by an earthquake, the isolators will allow the decoupling of the supported structure from the ground motion. After the seismic event, the restoring force due to gravity will bring it back towards the centre position. The performance of the device mainly depends on its radius of curvature and the coefficient of friction....
