Load Distribution Plate Calculation

Hello

I would like to know the method to calculate the size of a load distribution plate.

My problem:

my floor 3T/m²

load on a 9T pole (350x350x20 plate)

Thank you

attached is an essay but I don't know how to interpret the results

Is there no problem with your data?

you say

3 T /m² for soil resistance

and you're going to install 9 T / 0.1225 m²

isn't there like a big blem???????????????????

If I'm not mistaken, you'll need at least 3 m² of lift

since 1 m² = 3T

and this without a margin of security??????????

Hello

 

Yes, that's why we use a load distribution plate under the plate of the pole.

What I can't do is how to calculate the size of the load plate parting.

Have you really read my previous answer there is nothing that shocks you in this said answer

It seems to me very elementary a rule of 3

so your distribution plate should be at least 3m² without any security

with a thickness that prohibits deformation ( additional weight to be taken into account) therefore of your vertical growth of your post

 unless it is badly given in your statement

Hello 

I'm not sure I understood, your 3T/m² floor and your 9T posts, so I'd say 3m² of surface area for your plate  ; ), because 3x3 = 9 (+ a koef of security adapted to this application). But this seems too simple to me, shouldn't you take into account the height of your pole and the possible buckling under load? Its environment?. And of course, put gussets to better distribute the load.

Indeed in theory it would need a 3m² support. But it remains in the case where the plate is non-deformable, of negligible mass, and perfectly flat (the ground also by the way). In practice, this is far from being the case...

GT22 is right about an essential security coeff!

 

The part you enclose is 1m40x1m40 ep30mm (weight 500kg)

there is an inconsistency...

Hello

thank you for your answers

The attached file was an essay

I understand that my plate must have a surface of 3m² that's for sure. But in my case I need to know the thickness. Is there a rule for defining a load distribution plate?

Thank you

Thank you

thank you is not the answer to the problem posed

So if possible make sure that the answer that answers this question the most is defined as the best answer

so -1
