Product catalog summary
Seismic Protection Overview
The RESTON®PENDULUM Curved Surface Slider is a seismic protection device designed to decouple structures from ground motion during earthquakes. It operates on the principle of a pendulum, allowing horizontal displacement and shifting the natural period of the structure to prevent resonance.

Principle and Properties
The device functions by transmitting vertical forces and allowing horizontal displacements under normal conditions. During an earthquake, it provides lateral flexibility through sliding, dissipates energy via dynamic friction, and recenters the structure using gravity and design geometry.

Types of RESTON®PENDULUM
  • Mono (PM): Consists of a primary curved sliding surface, a steel element with ROBO®SLIDE, and a steel plate for rotations. The size of the sliding surface is based on maximum design displacement.
  • Duplo (PD): Features two curved surfaces for higher displacements with smaller dimensions, suitable for structures like bridges requiring significant rotational capacity.

Materials and Dimensions
The sliders are made from S355 steel, ROBO®SLIDE material, silicone grease, and stainless steel. A table provides dimensions based on vertical load and design displacement, with specific values for Mono and Duplo types.

Benefits
The device reduces dynamic impact, increases seismic safety, supports high loads, and is adaptable for new and existing structures. It is maintenance-free due to high-quality materials and corrosion protection.

Quality and Certification
mageba ensures high quality through ISO certifications and CE marking. Testing is conducted in-house and by third parties, ensuring compliance with European standards.

Installation and Maintenance
mageba offers global installation supervision and recommends visual inspections every 3-5 years. An installation and maintenance manual is provided with each unit.

Customer Support
mageba provides consulting for optimal seismic solutions and offers 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....
