Excellent and precise explanation with an example that I have been struggling to know the application of the wind pressure calculated until I watched your video. Thank you.
Nicely done, slides and presentation were clear .
Thank you! Let us know if we can provide you with any building envelope solutions.
Well done and easy to understand. Thanks for sharing!
Thank you for the feedback. Let us know how we can help. soprema.us/contact-us/
good explanation

Great video. In Fig. 30.3-2A, why didn't you choose GCp as a function of the Effective Wind Area?
Sir, can you share the link from which I can pull the basic wind speed ? I'm a developer and didn't know these stuff well but need to work on a system that uses this. Please help me with that.
@Faizan Amjad , ASCE 7 has an online tool that is extremely helpful. The link is asce7hazardtool.online/ .
is this directional procedure or envelope procedure sir ?
Why do we get GCp values when effective wind area of 1 ft^2??
For roofing we use a tributary area for the attachment of components between 0 to 10 sq. ft. Adhered components are considered to have a 0 sq. ft. tributary (fully adhered) and most fastened components go up to 1 fastener per 10 sq. ft. Rarely do you find roofing components with a tributary area of attachment more than 10 sq. ft. thus we use the left side of the graph (0 to 10 sq. ft. portion of the graph).
@@SopremaUSA So if I had a 20' long beam that is spaced about 5' apart that the roof rests on, then I should look at an effective wind area of 100sqft?
@@nicholastan2178 For the beam itself as a component , you are 100% correct. But for the fasteners connections, the area is very small. Example: For wood sheathing on the roof, the sheathing effective area is 4 x 8 = 32 sq.ft. However, for the component attached to it, which is the rafter spaced at 16" , the effective area is the rafter length x 1.33.
