Seismic dampers

Seismic devices such as Shock Transmission Units (STU), Fluid Viscous Dampers (FVD) and Tuned Mass Dampers (TMD) are vital for earthquake protection. STUs transfer dynamic loads while allowing slow movements like thermal expansion, while FVDs dissipate seismic energy, reducing stress on critical components.

The StrucPro platform is based on proven design principles from the bridge and rail industries, where performance, durability, and compact design are essential. StrucPro dampers are built for decades of reliable operation with minimal or no maintenance, thanks to our choice of high-grade material and unique long-life seal solution. Using high-strength steel, we’ve reduced their weight for easier transport and installation, without compromising seismic protection. Their compact size allows discreet integration into various applications, including bridges and structures or retrofits to historical buildings and monuments.

TMDs are designed to enhance stability, comfort, and longevity by minimizing sway caused by wind, earthquakes, or traffic. These systems improve structural resilience and minimize structural damage in case of seismic activities or other vibration complexity.

Together, they provide immediate resistance to seismic forces, ensuring stability and safety for bridges, buildings, and industrial facilities.

The StrucPro Series is a flexible and scalable platform, offering a capacity range of 200–3000 kN. Each damper’s characteristics can be easily adjusted to meet specific force and displacement requirements. Tuned Mass Dampers are purposely designed for installations in skyscrapers, bridges or turbines, reducing vibrations from wind, traffic and earthquakes.

StrucPro Series is engineered and manufactured to withstand nature’s forces in the harshest environments while meeting the latest design standards for earthquake protection of bridges and structures. StrucPro Series complies with EN 15129:2009 standards, ensuring quality and reliability for critical infrastructure applications.

Since many years, we have developed and customized dampers used for seismic protection of HVDC stations worldwide. Our viscous dampers are specially adapted to fit the existing frame design and will protect the substations from collapsing from sudden impacts of high forces and velocities in case of an earthquake. These infrastructure installations are most important to protect as to ensure distribution of electrical power to the community, especially in an emergency situation. But it is also very delicate as of the brittle components in the design. Therefore, we are especially proud our dampers are found to be the best for the mission! As additional proof we have tested and verified functionality for at least 75Million cycles and extended inspection intervals, to minimize maintenance cost and distribution losses.

With decades of experience from the high demands in rail and stay-cable applications, our dampers are developed to excel in any harsh environments. This knowledge has been integrated into the StrucPro and TMD designs, ensuring durability and reliability. StrucPro dampers and TMDs have been rigorously tested at third party institutes as well as in our well-equipped in-house testing facility and across temperatures from -40°C to +60°C, ensuring consistent performance.
