|~| 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.
What is the spacing between W8's? I try to keep the beam depths greater than
1/20 of the span, (1/20 of 23' = 14")
