Bill, There were a more than one reason for these failures (one being some cells with rebars not grouted at all :)). I did not investigate the relevance of these failures to the splice lap length, but would assume that these were inadequate as well. There was even a study (it is in the Northridge conference materials) correlating the direction and extent of CMU property wall failures with the direction and strength of the seismic forces. I also do remember inspecting a Kmart in Northridge when an aftershock happened and the roof and the CMU walls started falling down. But this was more of a cross-grain shear issue, I guess.
