If I'm modeling a building addition that has one side not exposed to wind pressure, how do I make sure that no wind is applied to that face in RAM Frame? I was considering not attaching my semi rigid diaphragm to the deck edge on that side, but I'm not sure if this will cause other issues.
Yes that would be good (reference Enhancement #120330)
We did enhance the user defined wind loads to support wind tunnel results in 15.04, but it's not quite the same as user defined pressures.

That's what I was expecting, thanks Seth. In the future, will RAM ever provide the option to manually enter wind pressures in modeler? I think this would be an incredibly effect, time saving tool.
Our program generated wind loads always assume a like amount of windward and leeward exposure on each rigid diaphragm. For cases where that's not true I recommend User Defined Wind Loads for accuracy. https://communities.bentley.com/products/ram-staad/w/structural_analysis_and_design__wiki/2052/ram-frame-wind-loads-faq
For semi-rigid diaphragms you can adjust the percentage on the windward vs. leeward edges with each user defined wind load case.
