Viscous Fluid Dampers

You can protect new or existing structures (building, bridges, towers etc.) against seismic, wind and thermal expansion by using Taylor Devices Viscous Fluid Dampers. The Dampers reduces stress and deflection because the force from the dampers is completely out of phase with stresses due to flexing of the columns. The viscous fluid dampers  literally soak up the energy induced motion, preventing structural damage as well protecting sensitive equipment inside the building.  Using fluid viscous dampers allows design engineers to reduce cost of the structure by utilizing smaller structural elements and less complex foundations while improving the dynamic performance of the structure.

 

Lock Up Devices

Lock-up Devices also know as Shock Transmission Units (STU) is a Viscous Fluid Damper with extremely restrictive orifices used to limit relative motion between masses during a transient event, while providing free motion in the normal mode. Example, on bridges the Lock-Up Devices allows motion when the bridge structure slowly expands and contracts thermally, yet locks the structural masses together under seismic or wind storm conditions.

 

Tune Mass Dampers

Tune Mass Dampers  is a device mounted in buildings to reduce deflection of the building under wind inputs by essentially applying force to the building in a direction always opposite to the wind-inducted motion,  Tune Mass Dampers are also in pedestrian bridges, ballrooms, stadiums and other structures to reduce vertical, lateral and/or torsional vibration caused by human activities and/or wind. TMD’s may be part of the original design or added later.

 

Toggle Brace damping Systems

Structures that have high rigidity, experience relatively small deflections and inter structural velocities under conditions of seismic, wind or thermal expansion, the Toggle Brace Damping System is the most feasible and cost effective option. This systems combines a fluid damper with a simple mechanical toggle brace assembly that magnifies the small displacement of the structure, while simultaneously producing the required damping force.

 

Cable Dampers

Taylor Devices  developed a line of passive damping devices specifically designed to minimize cable vibrations.  These devices provide continuous energy absorption and are designed for millions of cycles without maintenance requirements. Not only do Cable Dampers address stay cable vibration in a cable-stayed bridge, but stay cables may also act as a tuned mass damper in the control of deck vibrations induced by wind and traffic.

 

Seismic Isolation Bearings

Seismic isolation is a technology that protects the structure from the destructive effects of an earthquake. The Seismic Isolation Bearings decouples the structure from the ground and provides it with damping.  By Decoupling it allows the building to behave more flexible which improves its response to an earthquake. The added damping allows the earthquake energy to be absorbed by the seismic isolation bearings and therefore reduces the energy transferred  to the structure. Dynamic Isolation Systems (DIS) Lead Rubber Bearings (LRB’s) consist of vulcanized rubber layers that are laminated between steel plates to form a flexible structural support. This Base Isolation System  can be Designed and Modeled using software such as ETABS, SAP2000 and LARSA.

 

Non-Structural Isolation Systems

When Isolating an entire structure is not an option, or required  a Non-Structural Isolation System is a good option to protect vital equipment, artwork, or valuable statues etc.. A 3D Isolation systems designed and developed by DIS  offers both vertical and horizontal protection from a seismic event that meets or exceeds code requirements.
