Ramps between Parking Garages (AASHTO)
Ramps between Parking Garages (AASHTO)
(OP)
I am designing two parking garages side by side, but they are seperated by two "ramps" (each two lanes) that are about 400' long.
The garages are being designed for the loads specified in IBC (40psf), but my thought is that the ramps will need to be designed by AASHTO. Is that a typical assumption? Is there a special provision in AASHTO that would cover this as opposed to the main vehicular live load that exerts exceptional forces based on highway traffic?

You can certainly use AASHTO wheel loading as a guide - but most parking garages have a 7 ft. height clearance +/- and large trucks can't fit in there.
As far as code compliance with design - I also don't think AASHTO would apply. It is a ramp between garages, basically a building element vs. a highway.
Unless of course your DOT is part of the owner/funding for the garages - then it's up to them.
