CIRA Concrete Code 1920

CIRA Concrete Code 1920

CIRA Concrete Code 1920

(OP)
Does anyone here have a clue to what CIRCA is and were I can find a copy of it.  To the best of my knowledge it is a Concrete Code, but no one seems to of heard about it.

Thanks

RE: CIRA Concrete Code 1920

I believe that the word "circa" means "approximately" or "around"....in other words, if you see the term

circa 1920.....it means around the year 1920.

RE: CIRA Concrete Code 1920

(OP)
After futher clarification with the client I believe you are correct in saying that they are looking for information on concrete design standards from the 20's.  However in my research of things I can only go as far as the 50's.  Any help please??

RE: CIRA Concrete Code 1920

Contact the American Concrete Institute (ACI) or the Portland Cement Association (PCA), both should have some historical information for US codes.

All ready tried they only go as far as 56.  I've got a guy sending information from CRSI which is suppose to have information on evaluation of reinforcing bars in old reinforced concrete structures.

RE: CIRA Concrete Code 1920

jmendler,

I have the CRSI text your refer to (it is okay for the $10 purchase cost) but there is also a FREE Engineering Data Report #48 available in PDF format at CRSI ( http://www.crsi.org/PDF/edr_48.pdf ) . It covers similar stuff but no diagrams and plan drawings of the rebar/details of yesteryear.

You may have some fun with a 1920's building expecially if it was a flat slab. In the early 1900's there was great engineering debate about 2-way slabs without beams...C.A.P Tunner had a "mushroom reinforcement system" and there were other systems too like Kahn bars etc. But many were designed for much less than STATICS, like only 35% of statics yet they all withstood load testing.

Even upto ACI 318-1963 (not too long ago), it enabled you to design flat slabs for 80% of statics.

White Paper - The Criticality of the E/E Architecture
Modern vehicles are highly sophisticated systems incorporating electrical, electronic, software and mechanical components. Mechanical systems are giving way to advanced software and electronic devices, driving automakers to innovate and differentiate their vehicles via the electric and electronic (E/E) architecture. As the pace of change accelerates, automotive companies need to evolve their development processes to deliver and maximize the value of these architectures. Download Now
White Paper - Model Based Engineering for Wire Harness Manufacturing
Modern cars, trucks, and other vehicles feature an ever-increasing number of sophisticated electrical and electronic features, placing a larger burden on the wiring harness that enables these new features. As complexity rises, current harness manufacturing methods are struggling to keep pace due to manual data exchanges and the inability to capture tribal knowledge. A model-based wire harness manufacturing engineering flow automates data exchange and captures tribal knowledge through design rules to help harness manufacturers improve harness quality and boost efficiency.

White Paper - Modeling and Optimizing Wire Harness Costs for Variation Complexity
This paper will focus on the quantification of the complexity related costs in harness variations in order to model them, allowing automated algorithms to optimize for these costs. A number of real world examples will be provided as well. Since no two businesses are alike, it is the aim of this paper to provide the foundational knowledge and methodology so the reader can assess their own business to model how variation complexity costs affect their business.
