Cristopher D. Moen, Ph.D., P.E., F.SEI, former professor at Johns Hopkins University and Virginia Tech and now the owner of RunToSolve, is an expert in cold-formed steel (CFS) engineering, software and steel framing design automation. In a recent podcast hosted by Hari Magarabooshaman of Scottsdale Construction Systems, an SFIA member, Moen shared key lessons from his Ph.D. work on CFS framing and the launch of his structural engineering software company.
Unexpected Cold-Formed Steel Insights
In the early 2000s while working on his Ph.D., Moen studied thin-walled steel structures at Johns Hopkins University. Under the guidance of professor Ben Shafer, Moen uncovered unexpected insights on the performance benefits of introducing holes in steel studs.
“I discovered that putting a hole in a thin-walled member is not always a bad thing,” says Moen. “You can change the buckling mode and find a better performance, which was not well documented.”
This early breakthrough in structural behavior laid the groundwork forMoen’s approach to engineering and his CFS research contributions.
In 2019, after 8 years as a professor at Virginia Tech, Moen launched RunToSolve,. A company that develops CFS automation and simulation software.
“I learned that there was a strong need for better, high-performing tools to explore a design space more completely,” says Moen. “I became very excited about writing software.”
RunToSolve tools are designed to maximize efficiency, speed and accuracy. The digital tools enable engineers to explore a variety of design possibilities easily and comprehensively. Moen believes such digital tools support the construction industry’s growing emphasis on digital integration, sustainable design and cost-effective engineering.
CFS Automation and Simulation
Moen is an advocate for sustainability within the CFS industry. He views CFS studs and track as an essential component in sustainable construction practices. His current work focuses on leveraging his digital tools to enhance the efficiency of CFS design, which can minimize waste and reduce environmental impact.
Moen’s approach includes integrating automation and simulation technologies that help optimize material use. He believes that automation and simulation is realigning the steel framing industry, enabling innovative firms to produce cost-effective and sustainable solutions that meet modern environmental standards.
Moen says two emerging technologies in particular will transform the CFS framing industry:
- Advancements in joining technologies (clinches, rivets, welding)
- Development of higher-strength, more ductile and corrosion-resistant steels
Scottsdale’s advanced construction system employs rivets in its panelizing process, which fasten securely and won’t come undone.
Moen suggests that steel roll-forming companies should closely monitor and adapt to these trends to stay at the forefront of the industry.
Moen is also optimistic about the transformative possibilities of combining CFS with AI and machine learning. He says the potential evolution of codes and standards — the moving away from static PDF formats towards interactive, machine-readable formats — could streamline the steel framing design process.
“I see the use of interactive standards happening already,” says Moen. “Instead of having an equation, engineers will access a trained model, which will allow more accurate results, allowing engineers to model and analyze complex structures more effectively.”
This shift would place CFS at the forefront of sustainable construction, meeting modern demands for precision, efficiency and environmental responsibility, Moen says.
