Vibration of Wood Floor Sysytems 4

[connect2]

Hi All,
Is anybody aware of limits/criteria for acceptable vibration of wood floor systems? This particular residential floor is composed of 20' long proprietary wood floor trusses with an additional inch and a half of lightweight concrete topping. A review of codes and standards gives lots of comments about the need to satisfy/look into vibration control but not much info about what constitutes acceptable/unacceptable vibration and nor how to calculate as in found in AISC-11 Floor Vibrations due to Human Activity. It would seem that traditional deflection requirements of l/480 for a UDL or point load don't apply in the case of this particular floor. The Manufacturer has written all over the shop drawing system that their floor joist/system has been designed for code required vibration control but now that the floor and topping is installed it is noticeably 'Bouncy and Lively' to use the Owners performance standard/criteria.

Here's the article posted the usual way. Apparently I no longer know how to use my Dropbox account. Sorry for the multiple redundant posts.

The greatest trick that bond stress ever pulled was convincing the world it didn't exist.

I like the attempt to make it as simple as possible. I wonder how many guys have actually read it, or abide by it.
