Effective Wind Area ASCE
Effective Wind Area ASCE
(OP)
I have read many threads on this subject but I am still a little confused.
Say if a have purlins set at a distance of 1.2 m between each other and they are placed on top of girder trusses that are separated 5.0 m. The distance between my roof panel fasteners is 1.0 m.
In this case my effective wind area would be:
what is my effective wind area. Thank you so much for your help.

In this case my effective wind area would be:
- 1.2 x 1 = 1.2 m2
- 5 x 1 = 5 m2
what is my effective wind area. Thank you so much for your help.






RE: Effective Wind Area ASCE
The effective area for the purlins (tributary area) is 5 x 1.2 = 6m^2
Each is considered separately
