Reinforced Concrete column tie under axial tension load
Reinforced Concrete column tie under axial tension load
(OP)
Is it possible to splice (lap steel reinforcement ) the steel reinforcement in concrete column tie under tension load only , the splice length will meet the ACI codes . i.e no welding or mechanical connection to be used.

But you knew that. Why do you ask?

The only choice is to do splicing in traditional way , but if we did not follow the code in this case, what is the consequances ?????

Back in my previous life, we used to use Cadwelds (http://www.erico.com/products/CadweldRebar.asp) a lot. They are pretty slick and it says they don't need any special skills. Plus they're pretty cool when they're ignited. I'm sure you could get them if you order ahead.

I would not provide a lapped splice under a direct tension load. Being a column it is very much a uniform stress field in one direction, without small compression struts developing in the concrete to transfer force for one reinforcing bar to the next than a lapped splice cannot be achieved.

The answer is that the tie could fail suddenly and catastrophically. The reason for requiring positive splicing in tension tie members is to assure that a brittle failure of cover or bond doesn't result in sudden structural failure.
