Stealthy strength of cold-formed steel
Episode 187
Tuesday, 29 April, 2025
The seemingly outsized strength of cold-formed steel is not well-known. In this episode, earthquake engineer Ben Schafer, Johns Hopkins University, describes a research-industry collaboration with the automotive industry resulting in code changes for high-strength sheet-steel. Sheet steel has also been successfully tested in flooring systems. The upcoming CFS10 shake table test at UC San Diego is the high-rise building test for cold-formed steel. Schafer addresses misconceptions that structural engineers have regarding CFS: Basically: cold-formed steel looks too thin to be strong. However, with high-strength sheet steel, deformations do not correlate to lack of strength, which is something that automotive and aircraft engineers have long understood.
