1907 Reinforced Concrete Code? 2

[rsbmusicguy]

Hi All,

I am working on an old reinforced concrete beam that we believe is from the 1910s. We have no construction drawings or anything to go off of except the field measurements we have gotten so far.

I believe that the first reinforced concrete code was published in 1907, does anyone know where I can locate any of these old reinforced concrete codes? I have worked with a lot of old structures in my career and have used old codes but can only get back to the 50s.

Thanks!

You can check with the ACI and find out when the first codes came out. Canada's first national code came out in the late 40s, and it wasn't widely adopted. Codes in the US may have been earlier, but again it depends on if the jurisdiction adopted the use of it. Stuff, back then, was sometimes designed on 'rule of thumb' and also there were numerous texts published that were used for design methods. You are likely pre code. You likely have square or twisted bars for reinforcing.

Rather than think climate change and the corona virus as science, think of it as the wrath of God. Feel any better?

Not cheap, but not too bad, either, if you work with a lot of concrete building restorations/renovations/etc.:

ACI Historical Requirements 1908-2005

(And when you compare it the ADM, it's an outright bargain!)

these pages from Kidder Parker, 18th ed, may give you a sense of what you're dealing with. Compressive strengths top out at 3,000 psi.

Wow - thanks guys! I am going to look into these codes now and will be a huge help.
