I haven't read through all of the other responses, but since you are just looking for feedback I figured I would give mine to your original proposal. I don't like pricing option A or B because they both seem like pay per use to me and I also like to be able to see the details of the analysis as...
Thanks for keeping the discussion constructive and professional.
Last I checked, states weren't adopting or referencing the 1923 Peruvian Residential Code as a standard.
That's why I'm asking, I'm not saying my experience is the be all end all. I'd rather learn from the mistakes of others than...
Sorry, I'm not trying to slowly make any point. I thought I stated it before when I said the ACI318 and ACI332 commentary both say they are empirical in regard to temp and shrinkage reinforcement. If both ACI requirements are empirical, then they would seem to fall more under the category of...
SteelPE, has your question been answered? Seems like we aren't quite sure of the exact purpose of the reinforcing, but its definetely not enough.
Kootk, why .0018 and not .0025 or .002, whatever walls would require?
Are you seeing shrinkage cracks be a problem in residential?
So you are...
KootK,
So what are you recommending for the horizontal reinforcing in a concrete basement wall? I've always specified basically the IRC code minimum for walls 10' or less, which I feel is justifiable because its in at least three codes, IRC, ACI332 and PCA100. So I guess I just follow those...
I have seen plenty of vertical cracks, and they mainly appear to be shrinkage cracks. They typically do not have a horizontal component, but if they do, its likely because of a vertical spanning issue or a top support issue, not related to the vertical crack. The vertical crack could have been...

I think there used to be a requirement on the length between returns, along with more stringent requirements for top of wall anchorage, but it was removed in 2012 or 2015. The max length is/was something fairly extreme like 60' which would make the horizontal reinforcing pretty ineffective...
hokie66, in my experience, most builders have trouble even with the prescriptive code and understanding when it does and does not apply. So they still need someone like an engineer to help keep them out of trouble.
Aren't there also empirical and prescriptive sections in the IBC and other...
The commentary for the horizontal reinforcing section of ACI332 (Residential Code requirements for structural concrete) mentions the horizontal reinforcing is used to reduce cracking for temp and shrinkage basically. They are similar to the IRC horizontal reinforcement requirements. My opinion...
