Car shed, Roof uplift
Car shed, Roof uplift
(OP)
Hi,
For car sheds similar to these:

There is possibility of having the wind load acting on the underside of the roof, causing uplift force.
I found this pdf file that contains some helpful information,
h ttp://emer gencymanag ement.wi.g ov/mitigat ion/docs/1 432_final_ report.pdf
I use BS and I didn't find any requirements for such case.
I need your opinions/help on these points:
1)Is there any specific requirements in any code/ standard you know?
2)What would be the suitable percentage of blowing wind to be considered as uplift force?
3)Any suggestions regarding the load cases and combinations?
Regards

Also - the wind uplift is treated in our load combinations as just part of the wind contribution.
RE: Car shed, Roof uplift
Referring back to EN 1991-1-4:2005, I found that they are addressing the free-standing canopies.
However, they are only providing the pressure coefficients for "monopitch" and "duopitch" but for curved roof they include it only for enclosed structures.
I think I will have to adopt the values of "duopitch canopies" for the case of curved roof???
