Multi-mode vibration Control of a Floor System Using Tuned Mass Dampers

The composite floor system of a large multipurpose room on the third floor of the admission building at a state university exhibited noticeable vibration caused by walking. The composite floor system consists of three long and narrow bays. The vibratory attributes of the floor system established by numerical analyses and measurement revealed the presence of […]

Vibration Control of a Concert Venue Floor System Using Tuned Mass Dampers

Tuned mass dampers (TMDs) were used to abate resonant vibration of the floor system induced by the rhythmic (dancing) perturbation at an upscale intimate concert venue/night club. The composite floor system is made up of 2.5” lightweight concrete on 3” deep, 20 gauge steel deck supported by wide flange steel beams and girder framing. The […]

Vibration Control of an Office Floor System Using Tuned Mass Dampers

Foot traffic (walking) resulted in a vibration of the composite floor system on the 11th floor of an office building. The make-up of the floor system is slab construction consisting of 3.25-inch lightweight concrete fill on 2” deep, 20 gauge composite steel deck with the typical bay sizes of 30 ft x 30 ft and […]

Vibration Control of a School Floor System Using Tuned Mass Dampers

Floor Vibration Control Using Tuned Mass Dampers A tuned damping solution was developed to mitigate walking induced vibration of joist framed floors in twenty-five rectangular, trapezoidal, and irregular shaped rooms in an educational establishment. The make-up of the floors was concrete on metal deck, supported by open-web bar joists. The floors came in various sizes […]

Vibroacoustic Damping Using a Tuned Viscoelastic Damper

Tuned mass dampers (TMD) are highly effective and tunable passive vibration damping treatments. These devices are damped 2nd order systems appended to a vibrating structure; see Figure 1. Proper selection of the parameters (mass, stiffness, and damping) of a tuned mass damper, tunes the TMD to one of the natural frequencies of the underdamped flexible […]
