Steel, whether as structural steel framing or rebars in concrete work, is a well-studied highly documented and ubiquitous building material. Many pre-war buildings throughout the country, especially rust belt cities have historic metals, such as older steels, wrought iron and cast iron, which are not routinely studied in engineering schools and less documented in the general structural engineering literature.
In this article featured in the February 2021 Issue of STRUCTURE Magazine, Ciro Cuono and Christopher Ribeiro explore the history, development, and use of cast iron, wrought iron and structural steel in building construction in the United States. Learn more about the metallurgical differences, typical historic uses, methods for identifying different metals, analysis techniques, testing protocols, and examples of how to repair and reinforce elements in renovations and adaptive re-uses.
