EC1 : wrong height value to calculate area "F"

[Anonymous]

HI,

F area lenght is e/4, with e=min(b;2h)=min(27;2x7.80=15.60)=15.60m, so F = 15.60/4=3.90m.

RSA has taken h=4.62.

It means that I have to modelise the structure from ground to the top, instead of modelising from 1st floor to the top, to force RSA to take the good value of h?

thanks

Yes.

So, what is the aim of the parameter "altitude de la construction"?

[Artur.Kosakowski · Accepted solution]

If you model a part of the structure e.g. its top floor only Robot does not know if the part below is the same as the modeled one or the part you modeled is e.g. just the temporary small shed on the top of a sky scraper 

The structure height is therefore used for determining the value of wind pressure rather than calculations of F therefore in your case you should add two dummy 'outer columns' below your structure.

Other question : when RSA will be able to generate wind loads on a 3D frame?

EC1 are sufficiently detailed to get values for most common geometry.

Due to Autodesk policy we can not tell you any development plans and tametible.

Sorry.
