To address potential vibrations in the balcony system of a new, state-of-the-art, mid-size 2,150 capacity entertainment (music and event) venue, DEICON incorporated six tuned mass dampers (TMDs) into the 3-sided, 270-degree, wrap-around balcony, with bird’s eye view of the stage. When audience in music venues and theaters move rhythmically to music or performances, the dynamic […]

Upon having the construction of a new church near completion, walking induced vibration was perceived on a long span balcony. DEICON conducted on-site measurements and identified the first two natural frequencies of the balcony. In addition, the participating mass and the damping ratio of mode 1 of the balcony was evaluated. Tuned damping was used […]

Walking induced vibration of composite floor system of an office building was controlled at 4 bays, using 8 x 1500 lb tuned mass dampers (TMDs). The measured natural frequencies of the floor system were used in tuning the TMDs targeting the first vibration mode of two bays and first two vibration modes of the other […]
Read MoreVibration Control of Operating Rooms’ Floor System in a Medical Center via Stiffening and Tuned Damping
Part of an existing building was converted to a medical center with a number of operating rooms. Vibration Measurement of the bare floor system (without any fit-out) pointed to the first natural frequencies of around 6 Hz for various bays. Floor Vibration Limits of Operating Rooms: ISO standard suggests that vibrations in operating rooms not […]
Read MoreBalcony Vibration Control Using Tuned Mass Dampers
The irregular shape of three large, 1200 square feet, cantilevered balconies in a high-profile performing arts center resulted in areas at the balcony tip and edge susceptible to potentially annoying levels of vibration. To mitigate this effect, the building designers added tuned mass dampers (TMDs) to the underside of each of the three balconies. Following […]
Read MoreVibration Control of a Pharmaceutical Laboratory Floor System Using Stiffening and Tuned Damping
Extensive vibration measurements and numerical analysis of the 2nd floor of a pharmaceutical laboratory floor system conducted by the acoustics consultant of the project revealed that the vibration levels at various bays were well above the laboratory vibration criteria. In coordination with the structural design team, contractor, and client, a two-phase retrofit scheme was proposed […]
