Vibration Analysis in canopy
Vibration Analysis in canopy
(OP)
I'm in the process of designing open entrance canopy that has a cantilever of approx. 15'-0". It's been designed for the gravity and wind loads as per ASCE-7, however, I'm a little concerned about the vibration at the end of the cantilever under the wind loading. It's in a Hurricane prone region. I've done some research, but can't seem to find anything. Any advice or references on the subject would be appreciated.

Is your canopy a true cantilever or does it have hanger rods?

Assuming it is only the first mode you want to suppress using a small absorber mass ie. mass ratio less then about 0.01 then you need to tune the stiffness of the TVA to equal that of the natural freq. of the canopy.
TVA's are used in all recent major high-rise bldg's
