AASHTO Bridge Design 4th edition vs. 3rd edition Differences
AASHTO Bridge Design 4th edition vs. 3rd edition Differences
(OP)
What are the differences between the following standards:
#1 - "AASHTO LRFD Bridge Design Specifications, 3rd edition, 2004, with 2005 & 2006 Interim Revisions"
&
#2- "AASHTO LRFD Bridge Design Specifications, Customary U.S. Units, 4th Edition, 2007 (or the same in SI Units)"
I haven't designed bridges, so am not familiar with these books...and searches on the web and this site haven't helped. My problem is that #1 is cited by the NCEES as a 'Structural Design Standard' for the Civil PE and Structural I & II exams... h ttp://www. ncees.org/ exams/prof essional/p e_design_s tandards/s tructural_ design_sta ndards.pdf
However, I can only find #2 for sale anywhere...

If I buy #2 to study and take to the exams, will it be essentially the same as #1?
All/any advice/guidance is greatly appreciated - thanks!!

So I guess I'm stuck with getting the new book and hoping that I get close enough with it...

Since (1) is no longer being used for new designs, hopefully you should be able to borrow it. Do you know anyone who works either at a state Dept. of Transportation or a consulting company that does bridge design work?
BRGENG - I think both (1) and (2) are LRFD, just newer and older versions.
The AASHTO LRFD code is definitely still in flux, with at least one major chapter overhaul in each new edition. Sigh...

After a bit of hair pulling, my problem has been solved. Luckily AASHTO recently added this offering in their bookstore: "AASHTO LRFD Bridge Design Specifications, 3rd Edition with Interims, PE Exam Edition."
I'm quite relieved to have one less worry on the upcoming exam. Hopefully this (#1) will be the code to use for both April and October 2008 exams. The current rate of code shuffling sure can get exasperating...
...but Happy New Year to All anyway!

This whole changing of the codes really is a pain in the neck. I will freak out if i have to shell out another $240 for an older version.
I will say that there appears to be a huge difference between the new 4th edition and 2nd edition. It seems like in the new 4th edition alot of the design info is missing. For example, the moment and shear values for bridge spans in Appendix A in the 2nd edition.
Can someone shed some light?
Thanks

A subscription service for AASHTO interims and ASTM revisions would be good though. However, if they give you the updates free they'd probably just bump up the cost of the initial book...
