Parking Garage Live Load
(OP)
What live load is being used on parking garage design today? 40 or 50 PSF?
When was the last time you drove down the highway without seeing a commercial truck hauling goods?

RE: Parking Garage Live Load
IBC 2006 = 40psf
ASCE 7-05 = 40psf
IBC 2003 = 50psf
ASCE 7-02 = I can't find this code right now but I believe it is 50psf as well.
Note that you still have to consider all applicable point loads contained within your specific code.
RE: Parking Garage Live Load
- for garages with passenger vehicles only use 40 psf or the concentrated load noted in Footnote 'a' of Table 1607.1
- 50 psf for garages with bus or truck traffic.

IBC 2003/2006 is 40 psf UNreducible (1607.9.1.2) but the concentrated load requirements changed.
RE: Parking Garage Live Load
To answer your question specifically, when I was designing parking garages all the time, I used the 40 psf and reduced the column loads as allowed by code. None of my garages have failed yet.
As for point loads, I have seen an unsupported corner of a precast Doubletee fail under the 3,000 lbs test load.
I usually added 2 psf for mechanical loads.
RE: Parking Garage Live Load
Not yet, though we have only done a couple of garages since our local city adopted IBC 2006. It had been on IBC 2000 up until January of this year.
I'm sure, sooner or later, we will get called on this by the precast or post-tension supplier, then we will get pushed to go to 40 PSF.
