The course outlined the use of the simplified method for analyzing wind loads.
The definition specified in the course for enclosed buildings was slightly different from the one in ASCE At the end of the course, there was a quiz. One question was as follows: If a building is “Enclosed”, what does that imply?
And, I say, you might also not be able to use the simplified method wnd analysis.
Its an actual building I’m working on at the moment. I have a 3-page write up, a spreadsheet for calcs and wine sketches of the building. Too much to describe here, but can anyone help – I cant post my email, where can I post those documents for use on the forum? I’d like to figure out if my interpretation of the definition of enclosed buildings is correct.
I also want to check here before going off and telling the intstuctor he’s wrong. I may be the one who’s wrong here. Thanks in advance for any insight.
I would agree with you.

The best example is of a building where both sidewalls are completely sheeted and both endwalls are completely open. Note that in this case, care should be taken in determining the wind loads to apply to the bracing system in the longitudinal direction wid there may be more wind on the system than if the wiind was completely sheeted.
The key here is that “partially enclosed” will generate a ballooning condition due to internal pressure that neither enclosed or open will have.
That is the general rule for “enclosed”, however the wind-borne debris rules requirement for the simplified approach could mean that the building could be “enclosed”, but not qualify for the simplified approach. The instructor’s limits are probably appropriate for the simplified approach, but not “enclosed” in general. Here is the instructor’s definition for Enclosed Buildings: Building, Enclosed- A building that compiies with both of the following conditions: This is merely the converse of the requirements for Partially Enclosed Buildings.
At least, converse of two out of three requirements. That’s not what the code definition says. Briefly, for partially enclosed buildings, per the code, there are three tests: My example is not open on two sides but works the same way as yours. Whether or not you can use Simplified Method for load ssce is completely unrelated to the question winf whether or not it is enclosed.
There are a whole different set of requirements for that. I note that winx one accepts the instructor’s definition for enclosed structures, your example and mine do not meet the requirements for open, ,oads not meet the requirements for partially enclosed, and also do not meet the requirements for enclosed.
So, then, what would these two examples be? I believe I need to pose that question with the instructor.

ASCE Wind Loads – definition for enclosed structure ajh1, I agree with your comments, especially the note about “ballooning”, that is exactly what I think is the most important part of the three requirements for “partially enclosed” structures.
