RE: Load - Occupancy Live Load

[Subject Prev][Subject Next][Thread Prev][Thread Next]
No luck, Ernie. The building official took a stand - You can't guarantee the
future use of the area and, therefore, have to consider the code for worst
case condition. Yes, the actual usage for the space will prove a less than
50 psf live load, but there is nothing to prevent the client from taking out
the equipment and holding assembly's and aerobic training classes.
This means that the occupancy of the space must be changed and the area must
comply with the code rated live load for an assembly area - 100 psf.
Thanks for your input, but the BO is the final word on the issue.

|I've designed a fitness center open to the public on wood framed

|live load the
|original building was designed for is adequate for the fitness center. Like
|you said, it's not an assembly area and with access around each equipment,
|minimum 50 psf should be OK.
|I treat the equipment weight as dead load and I ask for their location,
|including rubber pads, leg configuration of really heavy
|equipments, dumbell
|racks, etc., and design floor framing for these loads plus LL(min
|50 psf). One
|thing I watch out for is if there is a long row of heavy equipment or racks
|that runs the same direction as the floor joist, it becomes
|critical for 2 or
|3 joist carrying a heavy uniform load along it's length. A revised
|layout may be necessary or some way to spread the loads to more
|joists if the
|layout cannot be changed.
