Hii, Thanks for sharing this information. Can you please tell me how can i calculate the base share and overturning moment from this pressure. Also can you tell me what is the procedure of shear wall Design by Perforated method
I believe when using positive Cp, you must subtract by the negative GCpi (subtracting a negative number yields a positive). The way you did it was underconservative
I understand that you want to be over conservative but do you also agree that you have to use the formula as described in the book? I believe there is a reason why the negative sign is in the formula to ensure that the results are more than accurate but not overly conservative. Thanks for your comment
@sherifhelaly3526 if you watch it closely, I’m plugging the values in the formula directly with their respective signs. The windward coefficient I used was also positive. Thanks for your comment.
When would you use MWFSR method instead of the envelope method? My understanding is the MWFSR method applies to the overall structural design, while the envelope method applies to windows, doors, or any non-structural components connected to the building?
Hi Omar Khan, thank you for your interest. I will be uploading a video on the envelope procedure soon. The MWFRS Directional procedure is based on the direction of the wind which is assumed to be perpendicular to the faces of the structure where as in the envelope procedure the direction of the wind “does not matter” and takes into account any possible wind reaction of the structure.

thanks a lot, very usefull information, need to see it twice...
Thank you Edgar

Their are load cases given just few pages down. When to use that
Hai. I need this wind calculation for flat mez roof building. Can you please explain

We need to consider negative cpi and positive cpi
It’s explained in the video
Exactly
@@bryarsleman2718 hai. You can give any training for steel design for me.
If you wanted to determine the uplift force on an attached aluminum open carport, would you use MWFSR? I think so.
Yes.
Why you took the -ve value of GCpi when calculating the pressure on the roof windward?

@@mathphyseng2002 Thank you!
Is is possible to get a pdf of the calculations
Not at this point, sorry! I lost the file.
Useful
Can you share the excel sheet please
Not at this point. Sorry I lost the file.
