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 […]

To effectively address the vibration issues of a monumental staircase in a healthcare educational facility, DEICON supplied and three tuned mass dampers (TMDs) and have them integrated into the structure. The TMDs were designed and calibrated to target the first bending mode of vibration of the staircase, thereby significantly enhancing its stability and ensuring a […]

Floor vibration of a grand ballroom subject to crowd loading is mitigated using tuned mass dampers along with stiffening.
Read MoreViscous Damping Devices Rebuilt
After 20+ years of operation, the 8 viscous damping devices of the 4 tuned mass dampers needed to be rebuilt. DEICON was commissioned to do this task by changing all the components of the viscous damping devices with their equivalent brand-new ones, testing the rebuilt units, and adjusting their damping coefficients.

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 […]
