superimposed dead load vs live load vs carpet storage

[MedicineEng]

Guys:
Need some help with how to address an issue of carpet storage:

I have to store for extended periods (months at a time)a big quantity of heavy carpet in a room , but before doing it I would like to be sure that the slab is not coming down with the weight.

According with the structural drawings, slab's superimposed dead load is 1.2Kpa and the Live Load 7.5Kpa. My doubt is where the weight of my carpet comes in: is it in the superimposed dead load or in the live load.
According with my understanding a live load is a temporary load in a slab, but nor sure if a long term storage of carpets is considered "temporary".

Thanks a lot for your help.

The carpets would be considered live load.

Just for reference, I look at the NDS (US Wood design code). For the wood design, a 10 year duration is associated with live loads (2 months for snow, 7days for construction, and 10 minutes for wind and seismic).

Agree that the carpet is live load. The slab, according to the drawings, has been designed for 7.5 kPa LL. But it has also been designed for 1.2 kPa SDL. Does that loading exist in reality? If not, I think you could logically use that capacity.

Being pedantic, you should use the abbreviation kPa rather than Kpa. Pa stands for Pascal.

Then the next question is...., how much does a roll of your various carpets weigh, how much floor space does that roll take up, and how many rolls high are you going to stack it? Everything else being o.k. with the structure and the floor system, you have to keep the stacked carpet rolls at less than 7.5kPa, with some consideration for impact loading if the fork lift guy drops the rolls into place. Then you might also want to consider that the orientation of the roll’s axis be perpendicular to the primary spanning members in the floor system, because a 3' dia. roll will produce a 16" wide line load.

Thanks a lot for your comments.
Hokie66, you're not pedantic and absolutely right.
I guess I just typed too fast and didn't recheck before submitting the post. Point taken.
