As a building owner or real estate developer, you know just how big of an investment owning a building can be. While disasters can strike just about anywhere, Taylor Devices provides a unique solution to protect your building through the use of viscous damping devices.
Originally developed for NASA in the 1960s, fluid viscous dampers have successfully transitioned to the civil engineering community for use in protecting buildings, bridges and other structures worldwide. Fluid viscous dampers, or seismic dampers as they are sometimes referred to, are hydraulic devices that, when stroked, dissipate the energy placed on a structure. This includes everything from earthquakes if you live on the West Coast, to wind buffering for high-rise buildings in major cities along the East Coast and Midwest.
Primarily used for buildings on the West Coast and along major fault lines.
Primarily used for high rise buildings on the East Coast and in the Midwest.

While living in an area without any threat of natural disasters is nearly impossible, living somewhere that is prone to seismic activity creates a unique situation. Most natural disasters such as tornadoes, hurricanes, blizzards, or floods, are typically associated with a certain season or can be somewhat forecasted. Earthquakes, on the other hand, are not. These natural disasters can happen suddenly and without warning. While earthquakes may occur less frequently than other natural disasters, they can be the most destructive and costly when they do.
Fortunately, building codes continue to be improved so we can be better prepared against the massive destruction these events create. In California for example, building codes have been modified after nearly every major earthquake.
Earthquakes & Code Improvements
Code improvement: concrete detailing
Code improvement: wood frame and soft story issues
Code improvement: welded steel frame detailing
While it is important to continuously update codes and make our buildings safer, this can take time. Several cities have begun implementing seismic ordinances requiring the upgrade of certain structures, but improvements can still be made. Did you know that current California Building Codes only require that buildings avoid collapse for people to evacuate safely? Current codes allow for your building to be designed for damages to occur, meaning it may not be functional or habitable after a moderate or large earthquake. And it’s not just California. Be sure to check your own state’s building codes to find out just how much damage can occur to your building. More importantly, as the building owner, you are responsible for life safety during and after construction is completed.
California Civil Code Section 1942 allows a tenant to break their lease without prior notice when the property is uninhabitable, such as if it has become damaged after an earthquake.
One method building engineers use to meet the required codes is to stiffen the building, which will make the structure stronger than the earthquake. While this will keep the building from collapsing, extreme shaking can still occur, leading to additional problems such as broken pipes and vents, toppling shelves and light fixtures, water damage, and more. These damages can lead to unsafe living conditions for tenants and you with expensive repairs.
An alternative and more efficient solution is to add seismic dampers to the building to absorb the energy of the earthquake. Similar to how shock absorbers work on your car when driving on a bumpy road, dampers can be added to a structure to limit the shock and vibration during an earthquake.
Taylor Devices makes it easy to retrofit existing buildings as well as protect new buildings from the harmful effects of earthquakes. Our devices allow for immediate occupancy after even the worst predictable design level earthquakes allowing your tenants to reenter their home or workplace after an event. Our seismic dampers will be immediately ready for the aftershock or next seismic event and will last the lifetime of the building.
These seismic dampers are a fraction of the cost it would take for major repairs, or even worse, the need for your building to be demolished because it is structurally unsound.
While fluid viscous dampers are great for protecting buildings from seismic activity, they can also be used for many other applications including reducing wind motion. Tall buildings will often experience unwanted swaying during high winds which can add stress to a structure and even cause motion sickness for tenants. Traditional methods are to stiffen the building, but this can come with added costs and weight. An alternative is a damped outrigger system that uses fluid viscous dampers. This solution is also superior to a tuned mass damper, which can be extremely expensive, very heavy, and takes away valuable floors at the top of a building.
