Vibrations Can Be Controlled – Wherever They Occur

Vibration Control for Structures

GERB Tuned Mass Damper (TMD) Systems for Long-span and Slender Structures

Structures such as bridges, skyscrapers, staircases, stacks, and antennas can all be excited to high levels of vibration from wind, earthquakes, nearby machines, or traffic. Low natural frequencies and low natural damping are typical for such structures. 

GERB Tuned Mass Damper (TMD) systems can significantly reduce these vibrations. They limit the displacements of structures by absorbing and dissipating vibrational energy. In general, GERB TMDs are passive systems and consist of 

 

 vibration masses, 

 springs or pendulums, 

 and Viscodampers®. 

 

Each device is custom designed for its respective application. To reduce vertical vibrations of large structures, GERB TMDs can be successfully designed for new construction or can be custom retrofitted for existing structures.

GERB TMD systems offer effective vibration protection and provide the following advantages:

 

 Simple, robust, and reliable technology

 Wear and maintenance-free structure

 No external energy supply required

 Adjustment of mass damper properties possible after assembly

 Space saving structure; low total costs
