There is a paper by Farzad Naeim called "Design Practice to Prevent Floor
Vibrations" (Sept. 1991) available for free download from AISC's web site
(http://www.aisc.org). Go to "Steel Info. Online" and then check out the
"Steel Tips". This paper may have what you're looking for.

Subject: Floor Vibration
I know I have it somewhere but I can not find it now. I have read a
paper where the natural frequency of a floor system was compared to the
level of comfort humans feel. I am looking at a floor system using W8
members to span 23 ft. The floor beams are on 5 ft. centers. The deflection
criteria of table 16A-D is meet however the system has a natural frequency
of 8 hertz. This seams low to me. If my memory is not to bad about 15
hertz is where humans feel comfortable walking on floors.
Thanks for any help.
