Open Building w/ Roof > 45deg
Open Building w/ Roof > 45deg
(OP)
Hello everyone,
I'm working on a pavilion with a 20:12 hip roof slope - super steep, super stupid (for Orlando, FL), but I digress. ASCE7-10 only has charts up to 45deg pitches. I have found nothing explaining what to do if you have a slope steeper than 45deg. Anyone have any suggestions or could point me in the right direction????? Thanks!
Also, mostly talking about MWFRS, but C&C info is also needed.

Check Figure 27.4-1 at the bottom. For roof slopes greater than 80%, use Cp equals to .8. I think it used to just say use wall pressures, but this is a little more accurate.

After speaking with some coworkers here, we have discussed just using solid wall pressures.

We have designed this using solid wall/sign pressures. It's definitely a lot more conservative than using the Cp = 0.8, which is good.
Now, we just need to figure out how to report the pressures on drawings for the C&C zones. Any suggestions?
