I was talking about the 3rd edition, but I have bought the 4th edition a few months ago to jumpstart my SE studying. The 4th edition is MUCH better for concrete, seismic diaphram & rigidity, as well as for steel. (The updated concrete column interaction diagrams are worth it if you can't photocopy a textbook.)
I will have to put my SEIII studying on hold though. I know that I didn't "fully" pass my CA special exams. When I get back to my mailbox from my vacation I'll find out the whole story on this. I'm pretty sure that I'll be retaking surveying though.
