Minimum Live Load - Structure on a Roof
Minimum Live Load - Structure on a Roof
(OP)
Hi,
Can anyone tell me what the minimum live load is for a roof structure (utility room, electrical room, supplies closet, etc)? It's not in ASCE 7-02 and not on any other forums, either.
Thanks!

Electrical room, 40 also (with wall panels only) unless there was heavy equipment, then look to the weight of the equipment, or 75 psf minimum.

Thanks for your advice.
Is there a minimum point load as an alternative?

Since this is likely a small roof area, most likely no live load reductions would apply.
If you check Table 4-1 of ASCE 7-05, you could probably rationalize a 2000 lb point load for your application, assuming I'm understanding your posting.
A sketch would be helpful.
