History and Basis of AASHTO Loadings
History and Basis of AASHTO Loadings
(OP)
Anyone know or has a link/reference, preferably dissertations or official archives of codes about the History of AASHTO Loadings?
Where they came from, and how are they derived, how are they studied to be the standard loadings for our AASHTO Codes?
For example, from MS-18, how did they changed it to HL-93 equivalent?
My take is maybe they are based on statistical data, bridge inventories, etc, but I need their study, if they have copy.
This is for my study on overloadings in bridges.
Thanks!

MS-18 is the live load that was used with the Standard Specifications. Find some old books on bridge engineering, early 20th C., @ Google Books. You'll find how the HS truck evolved.

Do you have any files/links/website in particular for this matter? I have been researching about this but still cant have any related topic. Or keywords on the search. Thanks!

To keep this thread alive, anyone know the reason on why lane load now are added to truck loads?
