thread194-243821: Concrete Plinth Design
Hi Engineers,
I'm about to embark on designing some plinths for some Cryogenic Plant (Nitrogen Tank, Compressors, Cooling Towers ect...).
Is there a publication (UK) which give design examples of such plinths.
I've got the Concrete Society's Technical Report 34, which gives design examples for 'Concrete Industrial Ground Floors', but I'm hoping there is some thing out there which is more specific to plinths.
Thanks in advance

Simply a concrete base for the Cryogenic Plant (Nitrogen Tank, Compressors, Cooling Towers ect...)to sit on.
One of the plints will be built on the earth/original ground, while the other will be built on a existing bund.
Hope that helps.

The Loading on the plinth will be 440KN/m^2, Soil Type is Brown clayey fine to meduim sand, the plinth will be exposed to all the elements (sun, rain, snow etc...)
The vessel that sits on the plinth has a cylindrical shape, with the base having the diameter of 3.2m and a height of 6.4m.
Cheers

Some of the established industrial companies have their own standard details for these items.

Kieran: Your spot on with the description. Good advice
hokie66: I believe piles may be the order of the day. I've got a geotechnical report to hand.
stanier: Earthquakes are a rarity in England, but it can be considered. What are your thoughts?
RE: Plinth Design
The above comments are good.
If founded on a pad with relatively low bearing values, you will be looking at a fairly large pad and possible differential deformations; a geotekkie is prescribed. It is possible to design a pad for this. If silt is present with the clay, you could be looking at frost heave problems. The foundation can be founded at sufficient depth or insulation can be used (considering the long term deformation of the insulation).
We have about 40' or so of good clay, albeit, highly plastic in our area and friction piles would normally be used. with an octagonal shaped perimeter beam, structured slab and piles. with a void under the slab (plastic clay kickin' in). We would also use a void form under the perimeter foundatio beam.
