design of precast chess table
(OP)
I am working with a precast concrete manufacturer who has installed some chess tables and chairs in a park. Some of the table tops have broken loose from the pedestals that support them. I need to engineer a conncetion between the pedestal and table top. Does anyone know of a standard that give any design loading criteria for this or similar conditions - picnic tables maybe?

2. survey top of posts and shim to exactly level w/ plastic or steel
3. place a bed of non shrink grout (very little water in the mix)
4. set the slab
5. attach clip angles w/ 1/2" hilti anchors.

if a vandal hurt himself, would he sue ?
but you should be able to think of a number (300 lbs sounds good to me) and double it (and you'll be twice as safe)

Possibly, up to a point. But what if the person is not a vandal as such, just someone in high spirits jumping on the edge of a robust looking platform.
I think there is some duty to ensure that the strength of connection is not too far removed from the rest of the structure.
I vote for the 600lb load.

Rebar in concrete does tend to have the right type of performance but resin anchors tend to result in shear failures so there is some clever working out to be done to firm up the concept - Good luck...
