RE: Wood Floors and Weights

[Subject Prev][Subject Next][Thread Prev][Thread Next]
    Someone pressing 200# should be the least of your worries if it is a true weight room.  A typical free weight tree (where they stack the weights) will be pushing 1000# over about 1 sf.  A dumbell rack can be 200#/ft with 4"x4" supports 6' to 8' on centers.  I have trained with guys that bench over 400# and squat over 600# (and yes they sometimes drop the weights); figure 2 200# guys standing 2' apart and one of them with that kind of weight on his back.  Another concern for "true" weight rooms is floor vibrations.
    If it is a weight room at someone's house, the country club, or a hotel, it's probably not a big issue.  I would keep the trusses at 16" on center, use a high live load, and specify a variable point load.

To all:


What is your general gut feeling for designing a wood floor to support a “Weight Room”?  I’m assuming at least some free weights.


The proposed floor system will be a rubber mat over 2 layers of ¾” plywood (edges staggered) over 24” deep wood floor trusses. 


I’m picturing some wanna-be governor pressing a 200# bar over his head then letting it free-fall 7.5’+.


Any thoughts?
