Wind Load Calculation on Walls | According to Eurocode | Tutorial

Wind loads on walls are required to verify the overall stability of a building, bending of facade columns and more. In this video, we show how to calculate the wind loads on walls, step-by-step. 💨💨

Could you please show and explain how Wind loads from Eurocode applied to Open structure like Pipe Racks or Cable Racks?🤔

[@samsokheng4488]

Many thanks. How about h>= 2b in EN1991-1-4, Figure 7.4 there are 3 levels of qp(z). Do we need to multiply Cpe with each faces (A,B,C...) with this 3 levels of qp(z) to obtain wind load at each of these 3 levels?

Hi,
Thanks for your good feedback!

This was a really great video and so helpful for a project that I am working on right now. I was wondering, is there any guidance for how to determine internal pressure co-officiants? That's something else that confuses me. I have read the code and know that essentially its either -0.3 or +0.2. Is this all there is to it?
This code is so confusing!!!

Hi Nabil,
That’s a good and tricky question as internal wind pressure isn’t that easy to understand. On a project where I designed suspended ceilings I used the coefficients 0.2 and 0.3 as you mentioned. However, when you have large openings in a building like a warehouse you should use the normal coefficients on walls if not even increase them bc of the increased pressure difference.

why did u take bigger value for width and smaller for length

And the load should be applied to the columns or the beams ?

[@structuralbasics97]

Hi,
That depends on the structural system. It could be that the facade is designed in a way that it’s supported by the floors. In that case the facade needs to be designed to resist that wind load. I have only seen cases where the facade was connected to the floors. However, in theory, the facade elements could also be connected to the columns. Then the columns need to be verified for the wind load.
In both cases, the wind load gets distributed to the floors and from there to the walls or stabilizing system. And then down to the foundation.

@@structuralbasics97 that makes sense, thank you for answering !!

[@structuralbasics97]

Happy I could help! ✌️✌️

what about for roof?

[@structuralbasics97]

We don’t have a video on that yet, but you can check out our blog post: www.structuralbasics.com/how-to-calculate-the-wind-load-of-a-pitched-roof/
