Wind Loading with Robot!

[TSOFA]

Hi,

I have to design a warehouse 20X30m that has trusses to both directions. The structure is  closed with panels at 20m sides (front and rear-no doors or windows), and at the long sides the structure is opened by 80% (only the top truss is closed with panel). 

- What is the best way to calculate wind loading?  by 2D/3D wind snow generation or by wind simulation?

-How I can distribute wind loading to purlins from panels?

- My opinion is that when wind acts on the long side, the structure's roof should be loaded as canopy roof (not closed building's roof). Is this something that robot will take into account?

-I haven't understand how robot takes in to account the wind parameters ( terrain, openings etc) in case of wind simulation.

- are there any tutorial videos for generating wind loading?

Thank you in advance,

I would check your wind loading code. I don't know of any code that currently supports wind simulation and my understanding is that it is not sufficiently tested to be supported.

With regards to Robot's built in wind generator this is again code dependent, most of my work is to Australian Standards which are not supported so I have to manually calculate and apply wind loads.

I am using Eurocode 1. Well, this was also my consideration. What I have finally done, was to create the wind loads for 2D/3D wind / snow generation. The problem is that along the long side of the building, the lower side purlins are overloaded. I think that Robot can not understant that the panel at long sides only covers the truss ( see model @ first post) and not the whole side. If you check the model that I am attaching, elements 229,235,242,248,255,261.268,274,281,287,294& 300 have really high wind loads. How I can correct this? I want to check the wind pressure (not linear load) of each zone but is confusing to do it by reading the wind and snow reports (please see attachents).
