I'm a starter structural engineer, and I'm trying to analyse the wind load for PV arrays, which will be mounted on an open steel structure from the sides and flatly full covered roof by the solar modules (the roof area is about 680 m2),
I want to get the wind pressure on the roof manually using ASCE 07 after distributing the columns and beams, and since I'm a starter I don't know from where and how to begin,
so your help is needed here our engineers, I'll be very thankful in advance for your help.
If I'm not misanderstanding the roof is flat. If the case is such that then wind load will not be distributed on the roof.
Please notify me if I'm not correct.
yes the roof is flat.
this steel structure will be founded on a stadium (which is no longer be used as a stadium),
first I have to design a steel frame, and then the PV modules will cover all the roof,
and the point which I need help for is how can I find the wind pressure acting on my structure???? specially the roof, because the uplifting forces on the panels will be high!
Note: all sides should stay open (will not be closed) and only the roof will be closed by PV modules
sorry, but I can't understand,
the required from me is to design a steel structure that will prevent the uplifting of the PV modules,
the structure is frame, and the PV's will be attached into the roof beams of the frame,
so can you please explain the distributoion of the wind pressure on the structure and PV's???
I'm really a stater structural engineer, I'll e very thankful for you
Can you post the DWG (AutoCAD Drawing)?
I wonder whether there is a gap between the PV and the roof of the steel structure or not. If there is a gap, the situation will be a matter of fluid mechanics (drag force around body due to flow of air).
