Wind : Importance Factor
Wind : Importance Factor
(OP)
Does a rooftop unit, mounted on a building with Importance Factor of 1.15, be also designed for I = 1.15 or can it be lowered to 1.0?
When was the last time you drove down the highway without seeing a commercial truck hauling goods?

Or if the OC is based on hazardous materials and the unit's failure wouldn't be detrimental to the facility.
These are stretches though that I might use to justify something existing.

As an example...all school facilities in Florida must have 1.15 factor applied. I design a lot of canopies for schools...1.15 applies for those, yet they do not usually impact the main structure.
If you have an AC unit on the roof and the building stands at the design pressure but the rooftop unit flies off and goes through one of the walls because it was designed at 15% less, well.....

Very difficult to do but it may be possible where the failure criterion is more serviceability than structural failure.
