Vibrations can be controlled – wherever they occur

Vibration Control for Structures

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. The use of GERB Tuned Mass Damper (TMD) Systems can significantly reduce these vibrations.

GERB Tuned Mass Damper (TMD) Systems limit the displacements of structures by absorbing and dissipating vibrational energy. In general, they 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 generally uses vertical mass dampers with threaded coil or tension springs. Leaf springs and pendulum suspensions are used for controlling horizontal and torsional vibrations. The performance of GERB Tuned Mass Damper (TMD) Systems can be demonstrated for new construction as well as for retrofitting existing structures.

GERB Tuned Mass Damper (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

In addition to Tuned Mass Damper (TMD) Systems, GERB also provides engineering, assembly, and inspection to solve your vibration problem.
