In a project our firm is involved with, the existing non-load bearing
CMU walls were removed leaving the CMU columns (16" square).  The
contractor has discovered that the existing CMU columns were not
constructed with the confinement ties that are shown in the drawings. 
One of the pricipal engiineers remembers seeing a paper on the use of
steel bands similar to crate banding to provide the confinement by being
wrapped on the exterior of the column.  The paper may have dealt with
concrete columns, but it would seem that this would be applicable to CMU
columns.  If this doesn't ring a bell, are there any other suggestions
for adding confinement ties?
