Bookstore Live Load
Bookstore Live Load
(OP)
I am working on a project that will involves a University Bookstore. What is a good live load to use? I was going to use 150 psf (Library Stack LL), but I am thinking this is a little too conservative. Any thoughts?

Minimum live load for retail or wholesale space is listed in the NBC as 4.8 kPa. Using hokie's suggestion, that would be good for book storage up to about 1.5m (5').
It might be enough, but it is limiting on what the bookstore can do. It would be cheaper to provide for 150 psf now than to beef it up later on. Talk to the client. See what he wants to do.

If you don't use 150 psf for "Stack Room", then what?
1. "Retail Store, Upper Floor" 75 psf with 1000 lb concentrated load, perhaps?
2. "Library Reading Room" 60 psf, maybe?
3. "Office Building" 100 psf?
An unintended consequence of any of these choices is that you now have the option (read that as obligation, IMHO) to apply live load reduction. Probably not a good idea for a possibly marginal loading requirement.
Of course you could arbitrarily assign a number that excludes live load reduction (101 psf to 149 psf), but that may be your worst option from a liability viewpoint.
My intent is not to convince you of one choice or another, but I believe that you have received high-quality advice from the other members.

Don't ever trust that the client will do what they say here. Stick with the code requirement of 150 psf so you can sleep at night when your imagination runs wild after reading this post.
The code is tanamount to a medical standard of care, and that is what we have to measure up to. Sadly, even that can be challenged though.

In real life, depending on the arrangement of the stacks, some beams may see the full design load while others don't, it is the nature of stacks, high load areas next to low load areas. Design for 150psf but use LL reduction if applicable.

Timing has a lot to do with the outcome of a rain dance.
