Floor Joist design

Floor Joist design

(OP)
Hi:
I need to know how to select the proper size wooden joists and their spacing for an 8 by 8 foot storage building that will house a very heavy object--  which is 32 inches by 42 and weighs 860 pounds.  Also, would a 3/4" plywood floor attached to these joists give sufficient strength to hold this object?  The floor frame (8' by 8') will be attached to  4 by 4 posts set in concrete, spaced 4 feet on center.
Many thanks in advance

RE: Floor Joist design

if there are no additional loading objects.....

I would use 2x8 SYP @ 16" OC
