Development Length error in AASHTO LRFD Bridge 7th Edition

Development Length error in AASHTO LRFD Bridge 7th Edition

Development Length error in AASHTO LRFD Bridge 7th Edition

Is there a development length error in the AASHTO LRFD Bridge 7th Edition (which includes 2015/2016 Interim Revisions?). I'm getting a much longer development length (6') as compared to the previous equation before the interim revisions (1') for a #5 bar. Is this correct? Or is there an error?

RE: Development Length error in AASHTO LRFD Bridge 7th Edition

Make sure you use all of the factors. Anything less than a #8 should have the same length as before, roughly. It follows ACI now...keep looking through the equations and commentary and you'll figure it out. I did the same thing at first.

Thank you BridgeEI. The page that contained λrc was misplaced, that's what made a HUGE difference.
