how to create a wind loading on a structure? 1

[anemesh]

how can I create a wind loading model on a building (roof and columns) having different pressures on different parts of the building (from EC1)? I tryed to use some shells but I don´t need stiff elements on my structure and even the shells can´t be ununiform loaded.
If you have any solution for this please say it.

Thank you!

If you want to apply a uniform load to a shell, select the shell and go to Assign|Area Loads|Uniform loads.

i know that, what I would like to know is how can I use a non-uniform load on a shell. like you know the wind pressure is non-uniform.

I'm two years too late to help you out...but if anyone else looks at this, just create "dummy" walls (stiffness modifiers set to zero) and apply a wind pressure coefficient to them (Select shell elements on one side of the building, apply area loads, wind pressure...). The elements may need to be meshed. This only works if the wind load case has been made with an auto-load (V8+). It will calculate the differences in pressure on the WINDWARD side only. This is because the side and leeward walls experience a constant pressure.
