I have kind of an interesting question. I am looking at a project where an existing CMU basement wall has been in place for 30+ years. It is very lightly reinforced. There are no signs of overstress. I do mean no signs. No cracking whatsoever etc. etc. We have the room and ability to install some new grout and reinforcing as 50% or so of the wall is un-grouted. It is an amazing thing to see. A whole new perspective on CMU.
Should bars be added to a Ko condition, which seems excessive in consideration of the history. Maybe add nothing at all, considering the wall has worked fine for 3 decades, or something in between?
