Non-contact lap splice question
Non-contact lap splice question
(OP)
I have a situation where the spacing requirement for a non contact lap splice can't be met. Can I just develope the reinforcing on either side of a potential crack? Essentially provide 2x the development length?

Going back to my previous question, could the reinforcing running in opposite directions be extended the development length past the point where the opposing bar is developed? so at any section, reinforcing would be adequately developed on either side of a crack.

1) In some locations, such as NZ, they have provisions for this. I've seen it specified that the lap should be the normal lap plus 150% of the extra distance between bars.
2) My personal opinion is that you can do this in the plane of the thing but not out of plane. With out of plane non-contact lapping, you generate a bursting stress on the concrete that is problematic. I've seen research pointing to this issue but I can't say that I've ever actually seen an explicit code provision to this effect.
I like to debate structural engineering theory -- a lot. If I challenge you on something, know that I'm doing so because I respect your opinion enough to either change it or adopt it.
