masonry horizontal joint reinforcing.
when using a #9 dur-o-wall horizontal joint reinforcing at 16" o.c.  what are the requirements for lapping this type of reinforcing at the corners?  is the mason supposed to buy a prefabricated corner section to use in these locations or is lapping allowed?
i can't seem to find any requirement in aci 530.1.

check out our whitepaper library.
with the ladder type, i generally lap it 'one rung' <g>.  i seem to recall dur-o-wal has a discription of the splicing.
