Interaction Diagram for 12"CMU
Interaction Diagram for 12"CMU
(OP)
Where can I find interaction diagram for 12" CMU wall. I was looking at NCMA TEK and found TEK 14-5A that is for 8" CMU walls. Any idea how can I find the same tables for 12"CMU?
Thanks
Thanks

The best part is you can input different rebar specs into your spreadsheet and it will recalculate the interaction diagram.

Often, the published diagrams are used as supporting material for designs, so it is a liability situation.
Creating something like a very wide application document for all conditions is a major undertaking especially with keeping it current to the new changes in the code standards and changes. Fortunately, the NCMA TEKs are written by the same people that do much of the codes, material standards and and documenting for the writing of the codes. The original ACI 530-02 was written using a 15 year old design standard and incorporating all research as support for the final document that was not legally published in 2002.
Industry references and codes are a true example of documentation for use in a "belt and suspenders" standard that mat be used properly or very irresponsibly. Codes and standards are just as slow to change. I can remember being on am ASTM material committee after 10 years of waiting to be a voting member and working for 5 years on a new material standard.
