ACI 318-05 versus 318-02
ACI 318-05 versus 318-02
(OP)
Hey all,
Are there major changes between the two ACI 318-05 and 02? I will be taking my SE I and II exam this fall and they require the 05 code. I have the 02 code, and they just released the 08 code. Buying the outdated 05 code at full price just for the test is not something I'm fond of. I've looked all over Amazon and Ebay for used 05 codes, and all are basically new prices. Is anyone familiar enough with the two codes to tell me what the major changes are? No one locally has the 05 code, they are either using the new 08 or are still stuck in the 90's with the old codes. Now if someone has one for sale cheap......

One significant change was to the strength reduction factor, phi, for flexure. The 02 code had introduced a limitation to phi within the development length of pretensioned strands to a maximum of 0.75 (to account for potential slippage and a brittle failure). If it was tension-controlled phi would normally be 0.9. This limitation within the development length could cause a dramatic step-wise drop in phi, and thus the flexural strength, at the end of the development length.
The 05 code (clause 9.3.2.7) allows phi to vary linearly from 0.75 to the full phi (up to 0.9 if tension-controlled) between the end of the transfer length and the end of the development length. This avoids the dramatic drop in the flexural capacity.

Buy the ACI Code. AASHTO's concrete section is adopted almost exactly from ACI. You might have noticed a footnote on the first page of section 8 of the Standard Specs that reffers you to ACI for what may be missing like Torsion or deep beam design. LRFD spaecs, section 5, are more comprehensive. I am a bridge person and have had to refer to ACI on occasions.
