Types of Seismic Isolators For Buildings

Bearings for seismic isolation devices as a layer of flexible system are set between the superstructure and foundation of the building to change the vibration characteristics of the building structure (prolong the natural frequency of the structure). During an earthquake, the deformation of the flexible system converts the horizontal shaking of the upper structure into horizontal displacement of the flexible system, isolating and dissipating most of seismic energy transmitted to the upper building structure, thereby greatly improving the earthquake resistance of the building (the isolation effect can reach 50%-80%).

Natural Rubber Bearing

Made of multilayer natural rubber and multilayer steel plates alternately, with good vertical bearing capacity and horizontal deformation capacity. (The support and connecting plate are vulcanized as a whole) Features: The support is processed as a whole, more reliable connection; Excellent performance; Longer service life.

Shock Absorbing Products

Shock absorbers for buildings, also known as seismic dampers or base isolators, are designed to absorb and dissipate the energy from earthquakes and other seismic activities, reducing the amount of damage a building may sustain. They work by increasing the flexibility of the building and reducing the forces transmitted through the structure.

Viscous Dampers

A viscous damping (vibration) device composed of high-strength metal cylinder, piston, guide rod, sealing element and viscous damping fluid.

Buckling Restrained Brace

A Buckling-Restrained Brace (BRB) is a type of structural brace used in buildings and bridges to resist seismic forces.

Friction Dampers

A Plate Friction Damper (PFD) is a type of energy-dissipating device used in structures to reduce the impact of seismic forces.

Mild Steel Damper

Apply automated workshop production, and strict quality management system to ensure product quality.

Viscoelastic Damper

A Viscoelastic Damper is a type of energy-dissipating device used in structures to reduce the impact of seismic forces, wind vibrations, and other dynamic loads.

Tuned Mass Damper

A Tuned Mass Damper (TMD) is a device used in structural engineering to reduce the amplitude of mechanical vibrations in structures such as buildings and bridges.

Eddy Current Dampers

An Eddy-Current Tuned Mass Damper (ECTMD) is a type of tuned mass damper that uses the principle of eddy currents to provide damping.
