Design the pads to be moved in the future.  Add a little more steel to prevent cracking during the move. No structural difference between a pad that sits on the ground compared to a pad that is 6 inches into the ground.    At least that is true for hurricanes in Florida. Not sure for earthquakes.

Hi PAN friends,

We are designing a sculpture garden and want to have two large-ish pads to hold sculptures on loan (to change every two years or so.) One pad would be rectangular 4’by8’ and the other round – about 6 feet in diameter. Both flush with the ground and artists could place a sculpture free-standing or drill into the concrete to bolt down.

The engineers are asking for some parameters to design the pads by:

Here are the design parameters that they would need:

1.       Weight – maximum weight and location of center of mass (horizontal).  This is important for seismic loads

As an example – 500 pounds with the center of mass 5’ above grade, acting in the middle 1/3 of the slab.

2.       Size – maximum height, width and length.  This is important for wind loads.

3.       Presumptive soil bearing pressures per the building code – 1,500 psf

 

Does anyone have suggestions? Guidance?

 

Thanks,
