MRI Equipment - Elevated Slab
(OP)
I am currently dealing with a situation where a client wants to locate an MRI equipment on the 3rd floor of a steel framed building.
The floor system consists of 2" metal deck + 3.5" concrete topping supported by W24 beams. The deck spans vary from 7'6" to 9'-6". The unit will finally be located straddling a W24x103 beam.
The unit is 14,000 lb with loads distributed through 4 legs (7" diameter). The legs are placed on a 36" x 30" square.
I have checked the beams and its connection to work, but I am having trouble getting the deck to work when the unit will be wheeled into place. There is a open terrace on which the unit will be delivered. The unit will need to move through at least 3 bays (with the largest span on 9'6") to its final location.
I am trying the metal deck point load distribution calculations (from SDI and NJB) but I find it difficult to justify FOUR 3.5k loads 3' from each other acting as individual point loads as opposed to a single 14k load. What do you guys think?
The building is currently partly occupied. I am not sure what is happening with the second floor.

Is that based on prior experience? If so what plate thickness and plate width would you recommend?
Will this plate be kind of a "carpet" for the unit to roll on?

I once had to do an entire schematic drawing of how this was to be laid out for the entire 200ft journey down a 1930s RC floor slab in an old VA. Fun...
