I have another question as I detail some
- If I use Couplers, do they need
to be staggered in a column splice?
- If I use lap splices, how are cross
ties handled? I have a rectangular shape column with several single
cross ties. Are the ties doubled, one for each bar in the
splice? If so, I would think couplers would be more efficient.

addition to the large bend radius problem that you mentioned, here are a couple
of more possible issues with large diameter bars:
Lap splices can get VERY long, therefor, make sure they fit in your
section (i.e. beam/column).
Related to #1 above, lap splices can cause significant congestion. In
some cases, especially columns, it is best to draw a cross section to scale. With
this in mind, you may need to use mechanical couplers. Note, however,
that mechanical couplers come in many different shapes and sizes and from my
experience the cheapest couplers tend to be the largest.

Large Rebar Detailing
I am detailing some concrete beams and columns with #10 - #14 bars.
I usually don’t detail these large bars. Are there any words
of wisdom someone can share about things to consider using this size bar?
I know one thing I saw in the past is the sweep radius of large bar hooks
can cause problems. Anything else I should be sure to consider? I
do have a beam and column joint to detail.
