Development length
(OP)
Lets say I have a rebar that I need to splice (transfer the tension force to another rebar), but the transverse distance (ACI 318 12.14.2.3) is too far apart. What are my options? Can I make the lap length longer?

For what you describe I often change the steel in the bottom bit so that the appendix D breakout cannot happen. Then you don't have a lap splice.

I researched this offset for a retaining wall failure with out-of-plane offset lap splice. I posted information in this thread: http://www.eng-tips.com/viewthread.cfm?qid=356939 . See the article from Washington State DOT on smaller diameter bridge pier connection to larger diameter caisson contained in the other thread for additional information.

Non-ductile failure at a load of 40% of what you thought it would be is not something to take lightly.

I thought there was something similar in ACI 318 as our code is based on the ACI code?
