Technical Notes
CRSI develops specific informational publications in the form of “Technical Notes” (formerly known as "Engineering Data Reports, or EDRs") categorized by [Structural] Engineering, Construction and Architectural. Technical Notes are free documents written to answer or to provide insight on specific topics regarding the design and application of reinforcing steel and how it relates to the construction industry. In addition, CRSI offers seminars based upon many of these and other topics.
Technical Notes and Engineering Data Reports that are currently available are listed by category in a quick reference guide below.
