Therefore using a 1. Thanks for the insight. If a building is “Enclosed”, what does that imply? User judgement is certainly in order.

All, I recently finished an online self-learning course on basics of ASCE wind loads, for continuing education hours needed for license renewal.

The key here is that “partially enclosed” will generate a ballooning condition due to internal pressure that neither enclosed or open will have. Windspeeds are site-specific for the location 7-022 and are found by interpolation of map contours to the lowds 1-mph.

I won’t reveal the source here. And, I say, you might also not be able to use the simplified method for analysis. My example is not open on two sides but works the same way as yours.

In this case, 1. I’m not trying to diminish your statement, its just that Lodas can’t say “WillisV told me so”. The only other transient loads would be soil, flood, etc. This is based on bringing the 50 year map speeds down to 10 year speeds. 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.


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? An underestimation of windspeed could result is a design that does not meet the requirements for minimum wind design loads for the building under consideration.

I have a 3-page write up, a spreadsheet for calcs and some sketches of the building. WillisV – appreciate your comments – but in the first paragraph you assert that live load is a transient load per the IBC But ASCE 7 indicates ultimate strength level forces for seismic load. At least, converse of two out of three requirements. This doesn’t seem right. By joining you are opting in to receive e-mail.

What is the limit on time that can pass? The Eng-Tips staff will check this out and take appropriate action. Essentially all loads with the exception of dead load and superimposed dead load can be classified as “transient” and therefore come under the umbrella of the 0. Rather it is intended to account for the reduced probability that the transient load will occur simultaneously – it is doubtful you would have a full live load during a hurricane for instance.

The ASCE commentary and your responses have been very helpful. Whether or not you can use Simplified Method for load calculation is completely unrelated to the question of whether or not it is enclosed. As an end note, the code recommends using 0.

So you increase There are no reference city or town locations on the ASCE 7 windspeed maps and while county boundaries are shown, the resolution is affected when the maps are expanded large enough to distinguish the boundaries and approximate the city locations. The reason this utility is needed is that the spatial resolution of the windspeed maps that are displayed in ASCE 7 are not sufficient to determine a site specific windspeed.

Back solving for T results in a return period of approximately years. Or alternatively, if you have some other design code that allows stress increases for wind, you’d use the calculated loads without the reduction factor. Promoting, selling, recruiting, coursework and thesis posting is forbidden.
