How to support a horizontal tank

[Peace10]

Hi everybody

I have a tank placed on a cradle of 3.6 m of long and I want to size the sole on which I will attach the cradle. which type of sole do I choise? and how can i calculate its dimension?

A lot of factors come into play. Does the cradle sit uniformly on the concrete pad or on 4 legs? how heavy is the tank when fully operational? What kind of soil?

At the risk of sounding preachy you need a geotech engineer to do soils investigation at the site to give you soil parameters, then you need to hire a structural engineer to design the concrete pad.

What you are designing is called a tank saddle. I agree with Jayrod...you need to know some soil conditions and the structural loadings to design both the concrete footing and the saddle. Assuming this is a steel saddle, you will have a high buckling load directly under the tank. The saddle base has to be large enough such that you do not impose too high of a shear load on the concrete and large enough so as to prevent crushing the concrete (not likely).

my tank is like this

I already found my loads applied on my sole & I want to know which type of Sole do I choise ( isolated sole or continues sole ) ?

As others said, you must look into the soil that you want to put the load on. It would be bad new to put a good tank on a poor soil and/or the wrong type of base support.

Depending in where you are, there may be some seismic factors. I doubt that the manufacturer includes those because they are highly variable.
