Re California:  Our practice is w/ respect to smaller structures and do not
have a lot of interaction with other engineers for masonry.  We partial
grout but only when reinf. is at 24" oc vert. x 48" oc horz.  At closer
spacing solid.  Ladder reinforcement for fences.  Be very specific about
which bars are vertical and which are horizontal.  We have had them put in
in reverse.

Subject: Masonry wall construction


I need some advice regarding regional masonry wall construction practices.

As I understand it, CMU walls constructed in California are all grouted
solid.  No partial grouting is used regardless of applied load. 
Is this true or false?
(The traditional rationale has been that all the seismic research has been
done only on fully grouted CMU walls.)

What is the practice of using ladder reinforcing as opposed to rebar in
intermediate bond beams?

What is the practice in Alaska?
