Taylor Devices Fluid Viscous Dampers are applicable to both fixed and base isolated structures, including buildings, bridges, and lifeline equipment. Diagonal brace dampers are available in output levels of 2, 000 pounds to 2, 000, 000 pounds force, with strokes of up to 6 inches. Base isolation dampers are available in output levels of 100, 000 pounds to 2, 000, 000 pounds force, with strokes of up to 120 inches. Standard output for both product lines is linear, where force is proportional to velocity. This allows damping levels as high as 50% of critical, offering truly dramatic seismic stress reduction in any structure. Optional output functions are available, including low damping exponents from 0.3 to 0.9, and relief valve damping offering an essentially flat response above a specified velocity limit. Special fluidic orificing can be supplied to allow thermal movement with minimal resistance while providing lockup for seismic events, thus creating a Force Transmission Device from this product line. For unusual seismic applications, adaptive or semi-active controls can be incorporated into any Taylor Seismic Damper. These products also have non-seismic applications as wind dampers on tall buildings, bridges and other structures.
