A Portable Tuned Mass Damper with Simple Tuning/Design for the Reduction of Vibrations in Civil Engineering/Architectural Structures

This IP consists of a device called "Portable Tuned Mass Damper (PTMD)" which is designed to be compact, portable, and easily adjustable. All parts of the device are screwed to each other to facilitate the construction and assembly. It can be installed within a building floor plenum, architectural elements or can be placed at the desired location directly or on the structure (such as a floor). It can also be placed within the architectural or ornamental elements of building such as planters, cabinets, etc.


Laboratory testing of the device has shown up to 85% reduction in the floor vibration when a 100 lb prototype was used on a 30ft x 30ft steel joist supported floor with a total weight of about 34,000 lbs.
