Wind Load Definitions in STAAD

Hi everybody =')

hope you all doing well,

mmm actually, I was trying to define wind load into my structure, which I had a difficulties in classifying it's type (open, partially enclosed, ..... etc)

My structure is looks like a monoslope roof, but with a photvoltaic panels on the top,

Now, my question is how can define the wind load as a member load If I have a wind velocity of 150 km/hr????

Also, what is the wind effect (wind pressure disribution) on the columns, main beams and the alligned beams????

here is a photo of the structure,

I'll be very thankful for you =')
