Minimizing perceptible floor vibrations is not all that hard to do, but it is more involved than just shooting for a cetain frequency. There is a brief blurb at the following link with a few references that will help you, including an article by Tom Murray in AISC's Modern Steel Construction and a link to the AISC design guide on floor vibrations (Tom is a co-author on that too).

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.
