Legacy building codes

Q. I'm analyzing a concrete moment frame building from the 1939-1940 era. I am trying to find the ACI building code used in the United States during that time. Was there an "ACI 318-39" or similar document?


A. In 1936 ACI published "The ACI Building Code - Building Regulations for Reinforced Concrete" (Tentative Standard). This document was superseded in 1941 by ACI 318-41, "Building Regulations for Reinforced Concrete".

If you need copies of those codes, there are two ways to get them:

- We sell all of the historical codes (1908 through 2005) in a packaged bundle on a USB memory stick

- If you happen to subscribe to our ACI Collection Online, the historical codes are included with that package (you have to select “Historical” from the titles list in ACI Collection Search).
