Rack Loads on Slab on Grade
Rack Loads on Slab on Grade
(OP)
I did a search here and found good information for rack column loads on slabs on grade for isolated columns.
What to do for back to back columns?
The Shentu research notes a radius of influence. In my situation the columns are within each other's radius of influence. How does this affet the capacity of the slab. The cited references do not go into this.
I am looking for Westergaard, Ringo, anderson infomration for this situation as well

My first thought was to combine the columns together on a single base plate and treat as a single point load.

Maybe you need to give us a bit more info on your exact situation.

the columns themselves are inboard a little bit and are 11" apart center to center.
I see this as two discrete loads

Any numbers or support for positive bending?
I could see that as well as negative bending.
I just need something to hang my hat on.
the concrete slab is existing.
the racks are ordered
the pallet loads are known
the only loading variable that I can control is the size of the base plate

AperlingPE, to get an idea of what sort of shape the slab will take, turn it upside down and treat the posts as columns and the ground reaction as a udl. Not accurate for analysis but it gives you a good idea on how it will tend to behave.
