Wind tunnel test results to Etabs

[engOFFG]

Dear Experts,

I received Wind tunnel test results from WINDTECk (Australia),for 80m height building ,not high-rise tower.
I expected to receive forces Fx ,Fy ,Mz at center of each floor diaphragm, but what i received is an excel sheet
for 4 case of loading (based on degrees) and pressure on numbered panels on bluing's 4-sides facade
see attached pic

number of panels is more than 200 ,I do not think i have to draw these panels on Etabs model then apply such pressures on them 4 times (for the 4 cases they offered).
inserted figures = 200x4= 800 figures (manually)

any ideas?

Use the detailed information provided by the wind consultant to create something simpler that can be reasonably fed into your design process. You can probably also create a post processing spreadsheet to massage the results that you got into the results that you want.

It might also be worth making a call to the consultant if you have't already. Usually, they'll have their information in a more data processing friendly format that they can share with you easily.

I like to debate structural engineering theory -- a lot. If I challenge you on something, know that I'm doing so because I respect your opinion enough to either change it or adopt it.

Yea, is there anyway you can manipulate the data provided to find the resultant force to apply to your model? you may be able to automate, at least a bit, a central coordinate and area for each panel. You could then find the moment about your diaphragm centroid by taking the moments about that point, and find total force by summing the appropriate panels in each direction. Once you set it up once it should be pretty easy to copy/paste for each floor. It also helps for if your center is to shift around a little bit.

Wind tunnel tests don't care about your diaphragms - would never expect them to do your lateral load distribution. I agree with the above - ask them if they can provide raw data that can be converted in excel to something usable by ETABS.

Looks like it from the table on the left, but may also want to confirm that these loads are MWFRS loads intended for structural design of the building. The diagram to the right looks more like a C&C study to me. Usually we'll get both separately. And the MWFRS comes as a lot more load cases than 4 (90 degree increments). We usually get 24 (15 degree increments). With only 4 cases are you actually getting both straight on and angled wind cases? Seems like you'd only be getting half of what you need, would think you'd need at least eight cases to hit straight on from all four principal directions and then all four angled cases. Or at very least 4 cases at 45 degree increments that are applied in either direction, positive or negative, not 4 at 90 degree increments.

Thanks to all of you

I sent inquiry to test provider, and waiting for response.

Dear MrHershey,
No it is not a C&C study , they stated this clearly in their report , I quote:

"Note that the panel pressure distributions presented in this report are applicable for the design of the structural frame of main building only,
and are not to be used for the design of the façade cladding. The results for the net pressures acting on the façade cladding are provided in a separate report."
