wind-open buildings h/L<0.25

wind-open buildings h/L<0.25

(OP)
Hello,
Does anybody know what happens in this case for open buildings? I have a monoslope free roof with an angle of 0 degrees. How do you calculate the wind loads if the h/L is less than 0.25 (in my case 26'/260'=0.1)? I can't use figure 6-18A from ASCE7-05 because that applies for 0.25<h/L<1.0. Thanks.

RE: wind-open buildings h/L<0.25

Just read your post. I am having the exact same issue with my design. Let me know if someone answers your question and I will do the same. Hopefully, they answer both.

RE: wind-open buildings h/L<0.25

Take a look at Fig. 6-18D and, in particular, Note 5: this addresses case of monoslope roof @ 0 degrees with h/L between 0.05 and 0.25. ...May also want to check out applicable errata: http://content.seinstitute.org/pdf/erratasheet7-05.pdf for some corrections/clarifications.
