Construction site hoarding with access gate according to Eurocode 1

[TWfea]

Hi everyone, I am working on a hoarding design (approx 100m long), and I have to include an access gate in the centre. I am applying Eurocode 1, section 7.4,.1 (free standing walls and parapets)

I was wondering how others deal with the wind load zones (A,B,C,D) at access points. The normal position of the gate is closed (and is the default position during a high wind event) so I would assume that applying zone D wind coefficient was fine. But if anyone out there has any feedback or a different approach I would really like to hear it, particularly any past experience!

I also have a related question that has popped up a few times on the definition of a "return corner"

1. The Eurocode illustrates a 90deg corner return, but if we have a 45 deg corner return this should go some way to counter the end effects, but should i handle this.
   • Should I treat the 45-degree return as an end since it's less than 90 degrees?
   • Or should I interpolate between the "no return corner" coefficients and "return corner" coefficients?

If you need any more detail, just let me know!

You cannot apply zone D for the whole wall. You are expected to assume the gate is open and design for two separate walls and apply zones A,B,C,D

The Eurocode illustrates a 90deg corner return, but if we have a 45 deg corner return this should go some way

Pls provide a sketch . You are expected to consider different wind directions . Figure 7.19 shows that , max load occurs at 45 degr. skewed wind direction.
