Firehouse - Attic Space Live Load?

[jparisi]

Designing a Firehouse

First Floor consists of living space(kitchen, sleeping quaters, etc.), large meeting room, and attached 4 door apparatus bay.

Second floor is ONLY above living space and meeting room. There will be attic trusses and it will be used for storage of general noncombustible materials.

What can we classify this space as, Storage?, R-2?

If it must be storage, then we need LL=125psf and that would require much more design and heavy beam members to support bottom chords.

Hoping we can just classify as R-2 and treat as residential storage and use LL=40psf or 50psf.

ANY SUGGESTIONS???

If its a fire station it's a Group B occupancy, so you need to select the appropriate structural loads based on this occupancy.
