ASCE OPEN BUILDINGS h/L>1?

[tmgczb]

As the title, how to determine the wind load coefficients for open buildings of which h/L is more than 1?
There are wind load coefficients for open buildings with monoslope roof, pitched roof, 0.25<h/L<1 in ASCE 7.

Generally the limits are from the configurations actually tested in wind tunnel testing. If it falls outside of that range, then theoretically that information needs to be obtained through a wind tunnel test. Your best bet would be to check the commentary if they offer guidance.

Other than that, check other design codes for guidance and failing that published literature to derive a value that would be conservative.

Thank you very much for your reply.

Now I am trying to consider this issue from another way:
For open buildings,h/L<1,of which the horizontal dimension is not too small, the wind load coefficients varies,usually 2 values for each load case.
In case h/L>1, the horizontal dimension of the building along the wind direction is not as big, we do not need to apply 2 values.
In this case, I am trying to consider the building as an "other building" as Chapter 29 in ASCE 7-16. Or if still considering open buildings, I think 1 value for each load case is enough.
