Airplane Bridge Design Guides
Airplane Bridge Design Guides
(OP)
Are there design guides available for the design of bridges to carry airplanes rather than vehicles? In particular I am looking for slab and girder wheel load distribution factors similar to those found in the AASHTO manuals for vehicular bridge design.
Thanks for your help.

They have criteria for airport design.

The section of the manuals on pavement data should either have what you need or reference the appropriate standards that will have what you need.
Aircraft Planning Manuals and Product Brochures
These documents provide, in an industry standardized format, airplane characteristics data for general airport planning. Sections within each document include: Airplane Description, Airplane Performance, Ground Maneuvering, Terminal Servicing, Operating Conditions, and Pavement Data. Boeing should be contacted for any additional airplane information required not covered in these documents.

According to my AASHTO manual the wheel load distribution factors for concrete on steel I-beam stringers and prestressed concrete girders is based on "Design of I-Beam Bridges", by N.M. Newmark, 1948. I have not read the article, but I would be concerned that the d.f.'s would apply to the large airplane wheel loads.
Any thoughts?

As per "bridgebuster"'s suggestion, ACI343R-95 may be of assistance, particularly section 5.10 "Airport runway bridge loads". Table 5.10 has aircraft loads and wheel spacing info. Section 5.10.2 has info on relevent impact %.
Section 5.10.3.2 has a bit of info on load distribution.
I like the text "BRIDGE DECK BEHAVIOUR" by Hambly that deals exclusively with deck modeling and load distribution.

I didn't say we used AASHTO or the factors prescribed therein, I explained that with data from either manufacturers or the specs from FAA regarding the tire footprint and load distribution (how much the front wheel loaded and the back) and using the distribution studies done by the FHWA (the FHWA has funded many studies to ascertain the behavior of various bridge decks under live load) to support the work of Newmark you can then apply this to distribution of aircraft wheel loading.
Lastly, Newmark used surface influence lines to establish the distribution factors noted in AASHTO - You should read his work.
