Monumental Staircase Vibration Abatement Using Tuned Mass Dampers-5

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 […]

Viscous 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.

Vibration Control of Long Span Balcony in a Church Using Two Tuned Mass Dampers

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 […]
