Preparing to take the Structural I exam again and I notice that they have updated the required codes for the test from the 3rd edition to the 4th edition (2008 Interim).
My company does not do a lot of bridge work and therefore does not have updated AASHTO codes on hand.
Before I invest in my second copy of a reference I use solely for a test, I wonder if someone familiar with the two codes can enlighten me on what the changes are between the two editions of the code. Perhaps there is a document somewhere listing the updates? Do the updates between editions generally only further clarify points or do they introduce new factors, methods, and requirements?
