The vibration mitigation products produced by our company mainly include the following types:
Viscous Fluid Damper
A viscous damper is a kind of oil cylinder structure filled with damping medium. It drives the flow of the internal medium through the reciprocating motion of the piston to produce a damping effect, and then converts kinetic energy into thermal energy as an energy-consuming and shock-absorbing device.
Buckling Restrained Brace
The buckling-restrained brace (brb) consists of three parts: A steel core, restraining components, and isolation materials. The middle section of the steel core needs to be processed into a working section with a reduced cross-section, which can yield and dissipate energy when reaching the preset deformation.
Advantages of Vibration Mitigation Products
Viscous fluid damper have many advantages, including:
Substantial stress reduction: Greatly enhanced damping lowers both stress and deflection throughout a structure. This allows the structure to remain elastic.
Easy to model with existing codes: These dampers are completely viscous in output and will simply and efficiently raise structural damping to 20%-50% of critical, versus 1%-3% for a typical non damping design.
No maintenance ever required: Devices exclusive modular design uses a minimum number of moving parts. Patented seal has a history of over 50+ years of successful performance on demanding applications.
Environmentally proven output: Thermostatically controlled, virtually unaffected by temperatures from -40 degrees f to +160 degrees f. Nonflammable inert fluid and stainless steel piston rods standard on all models.
High damping rubber bearing have many advantages, including: Buckling-restrained braces have energy dissipative behavior that is much improved from that of Special Concentrically Braced Frames (SCBFs). Also, because their behavior factor is higher than that of most other seismic systems, and the buildings are typically designed with an increased fundamental period, the seismic loads are typically lower. This in turn can lead to a reduction in member (column and beam) sizes, smaller and simpler connections, and smaller foundation demands.
Application of Vibration Mitigation Products
Viscous Fluid Damper
Viscous fluid damper can be used for a variety of purposes, including: Viscous dampers are mainly applicable to bridges and high-rise buildings in areas where earthquakes and typhoons occur frequently.
Buckling Restrained Brace
High damping rubber bearing can be used for a variety of purposes, including: A buckling-restrained brace (BRB) is a structural brace in a building, designed to allow the building to withstand cyclical lateral loadings, typically earthquake-induced loading.

Fluid Viscous Dampers Are Incorporated in a Variety of Systems
Damped outrigger
Outrigger systems are commonly for wind applications used in tall buildings to provide lateral stiffness to the building by connecting the stiff core of the building to the perimeter columns.
Direct acting damping
A direct acting damper system is when fluid viscous dampers are integrated into a building or bridge’s structure to help absorb energy due to wind, seismic events, or pedestrian activity.
Base isolation systems
Base isolation is a method of seismic protection where the structure (superstructure) is separated from the base (foundation or substructure).
Three major components of a BRB that can be distinguished are its steel core, its bond-preventing layer, and its casing.
The steel core is designed to resist the full axial tension force developed in the bracing. Its cross-sectional area can be significantly lower than that of regular braces, since its performance is not limited by buckling. The core consists of a middle length that is designed to yield inelastically in the event of a design-level earthquake and rigid, non-yielding lengths on both ends. The increased cross-sectional area of the non-yielding section ensures that it remains elastic, and thus plasticity is concentrated in the middle part of the steel core. Such configuration provides high confidence in the prediction of the element behavior and failure.
The bond-preventing layer decouples the casing from the core. This allows the steel core to resist the full axial force developed in the bracing, as designed.
The casing – through its flexural rigidity – provides lateral support against the flexural buckling of the core. It is typically made of concrete-filled steel tubes. The design criterion for the casing is to provide adequate lateral restraint (i.e. rigidity) against the steel core buckling.
Welded connection: The brace is fully welded to the gusset plate in the field. Although this option requires additional man-hours on-site, it can increase the performance of the brace itself by improving the force transfer mechanism, and potentially lead to smaller braces.
Bolted connection: The brace is bolted to the gusset plate in the field.
Pinned connection: The brace and gusset plate are both designed to accept a pin, which connects them to each other and allows for free rotation. This can be beneficial to the design engineer if he or she needs to specify a pinned-type connection.
