For over a century, GERB has been a trailblazer in vibration isolation and structural motion control, assisting engineers and architects to protect some of the world’s most demanding structures. From slender skyscrapers and long-span footbridges to monumental staircases and critical infrastructure, GERB offers innovative Wall Dampers, Tuned and Active Mass Dampers (TMD and AMD) and 3D Base Control (3D-BCS) systems that enhance structural performance, occupant comfort, and seismic resilience.
GERB Viscous Wall Dampers (GVWD) are engineered to dissipate wind- and seismic-induced motion through distributed, floor-height viscoelastic dampers, while GERB TMDs operate exclusively at a structure’s natural frequency.
Applications range from mitigating perceptible sway in tall buildings to reducing vibrations in long-span floors, monumental staircases, and pedestrian bridges where comfort and serviceability are critical.
GERB has further innovated existing TMD technology with its Low Friction Rail System (LFRS) technology for projects with limited installation height. GERB’s TMD systems operate without hydraulic dampers. By utilizing proprietary mechanical damping technologies, the LFRS provides highly reliable motion control with virtually maintenance-free operation over the life of the structure. This makes LFRS TMDs especially well-suited for tall, slender buildings and retrofit applications where compact design, long-term reliability, and minimal maintenance are essential.
In addition to motion control, GERB is a recognized leader in seismic and vibration base isolation for both new construction and retrofit applications. Its 3D-Base Control System (3D-BCS) technology uses pre-stressable steel spring isolators and viscous dampers (Viscodamper®) below structures to reduce the transmission of structure-borne noise, vibration, and earthquake forces in all spatial directions. Through close collaboration with architects, structural engineers, and developers, GERB continues to advance vibration and seismic protection technologies for resilient, high-performance structures.
