ACI 318-41 Building Regulations for Reinforced Concrete

[GreatBruce]

I need to investigate a foundation built in 1941. Anyone has any information or reference which can help me figure out the foundation built in that age. Thanks so much. Bruce

I have one book by Gottschalk, an argentinian edition that I think followed closely the ACI code.

Gottschalk, Otto. Hormigón armado, teoría y práctica — Buenos Aires : El Ateneo, 1943 . — 360 p.

I have it in the cabinet I better do not access but maybe thrice a year so I do not promise help by looking that book. Anyway I can comment that I did a check for a column in the 2000 kip range with this book and other than you should be using strength of the era (about 10 MPa fc or just above it) the results were quite conform with ordinary practice by now.

Also, for such old footings you can find they are not reinforced. Than you will need to resource to the flexural (and/or tensile) strength of concrete, and some current evaluation of its standing actual value (experimental) wouldn't be then unwarranted.
