It has always seemed to be to be contradictory to continue the reinforcement across crack control or expansion joints. You put the movement joint at a location so as to concentrate the movement at that location then you connect the two sides with a relatively rigid joint. It seems to me that there are two defendable design methodologies. 1) Stop all reinforcing at the joints and allow the joint to move. 2) Run the reinforcement continously and remove the joint. If you put sufficient reinforcing in the masonry then the cracks will be small enough to be of no concern. This is the principle applied when they build reinforced concrete roads over a thousand feet long. Do you have any experimental data availible to say how the joint works with the continous reinforcement? Could it be that the reason that there have not been problems with running the reinforcing through the joints be that the joints were not really needed? Mark Gilligan S.E.
