It is often quite difficult to eliminate annoying floor motion that results from human activity. Many past methods have proven to be either ineffective or economically and architecturally prohibiting. Although tuned mass dampers (TMDs) have been used to control floor movement, their success has been limited. This is primarily because peak floor vibration amplitudes are usually less than 1 mm (0.040 in.) and dampers require a much greater amplitude to dissipate energy. This paper presents a multi-celled liquid damping device supported on a steel plate together with the necessary mass that appears to be an effective solutionPublished
