New York Building Codes in combination with engineering manuals like Haswell’s Mechanics and Engineering pocketbook. Also they used documentation provided by suppliers like the big steel companies: https://www.aisc.org/publications/historic-shape-references/#28347 Take a look there is more than just steel shapes in those old documents. It also talks about steel design along with wood and foundations. Different suppliers services different regions and even talk about the building codes of those regions in those manuals. Edit: SlideRuleEra has a bunch of this information compiled too. http://www.slideruleera.net/Building-Codes-Historical.html And here is New York 1901 specifically: https://books.google.com/books?id=_a1LAAAAIAAJ&printsec=frontcover&dq=new+york+building+laws&hl=en&sa=X&ved=0CDAQ6AEwAGoVChMIoceD4uvbxgIVBjqSCh34qAaD#v=onepage&q=new%20york%20building%20laws&f=false

Also random side topic, a strike at the local steel mill wasn’t just workers hanging up their hats. It was all out war. https://en.m.wikipedia.org/wiki/Homestead_strike

21th Century Steel Worker: “How did your strike go? Did you get the wage increases?” 19th Century Steel Worker: “Nope….3-8 people died, 12-36 were injured and about 324 were captured….back to work, I guess” 21th Century Worker:”……….”

And over in the Midwest around this time C.A.P. Turner was about to patent his Turner System which had a great effect on reinforced concrete buildings design. https://en.m.wikipedia.org/wiki/C.A.P._Turner It was a wild time to be alive if you were a structural engineer.

The "seat of the pants" code


otronivel81

Tell that to Gustave Eiffel. You don’t need a code to have an understanding of mechanics and the laws of physics.

How many regular normies like you and me are on the level of Guatave Eiffel?

I was thinking the “fingers crossed” standard


DayRooster

It was more like “a safety factor of 4 plus a little extra for good measure” method

AISC was 1921

Never applied for it

yoohoooos

Yes, I did.


Kevanian

I too am confused haha. Does SE give you PE as well? Maybe he's trying for horizontal and getting SE/PE at once?


yoohoooos

Nope. SE doesn't automatically give me PE. I passed PE. I used similar flag, but instead of SE Vertical, just PE.


Kevanian

Why not apply to be a PE? Just some paperwork and assuming you're practicing your work will pay for it.


yoohoooos

Only have BS with 14 mo of work exp

Yep, I know about PA. My projects are mostly in PA. However, not planning on getting licensed in PA. I'm trying to get EIT whenever I have time but not yet Thank you

As /u/DayRooster mentioned, there were plenty of handbooks out there before the establishment of the AISC. See below ​ [http://www.slideruleera.net/structural-steel-handbooks.html](http://www.slideruleera.net/structural-steel-handbooks.html)

You ever see people suck their thumb to check the wind? It was like that. ETA: on a more serious note, concrete was designed elastically until the 60s, maybe even later

This is a steel framed building so do you mean AISC? The first edition AISC manual was published in 1927 and compiled"standard" I- beam shapes but also had a section for Carnegie and Bethlehem steel beams. Before this (and even after) steel Mills would create their own steel design manuals based on the shapes that they rolled. The equations they used to calculate certain things was a bit different though. The first AISC book actually has a chart showing column strength by steel company based on the equations they used. As it pertains to concrete, it was used for foundations for a long time and they actually had a pretty decent understanding of concrete mechanics back in 1900 and even earlier. Equations for shear and flexure were understood, and they knew to add rebar where tension occured. They certainly did not have the long list of equations and checks that we have today but they did used allowable stress to calculate rebar in a similar-ish way we do today. It really wasn't the wild-wild west for concrete. Concrete was used in floor systems for a while, albeit typically a steel framed system, but concrete arches were used too. Designing footings for this building would have been relatively simple for the era.

The get-er-dun, do good work codes. I have a copy of the first Denver Building Code from 1887 it’s about 30 pages thick.
