In this episode, we talk with Ben Moerman, P.Eng., M.Eng., Ph.D., and project structural engineer at StructureCraft, about earthquake-resistant designs and sustainable construction with mass timber. He shares insights on how mass timber can enhance safety during earthquakes and the challenges it poses compared to steel and concrete. We also explore new technologies for earthquake-resistant structures and sustainable building practices.

Here Are Some of the Key Points Discussed About Innovative Ways to Incorporate Mass Timber in Earthquake-Resistant Designs:
Ben pursued a master's degree in earthquake engineering to specialize in seismic design and mass timber. He chose Oregon State University and the University of Canterbury for their strong programs in these areas, and was particularly drawn to Canterbury's expertise shaped by significant earthquakes in 2010 and 2011.
Ben was drawn to Canterbury's research on post-tension timber systems for low-damage design, which inspired his work to improve cross-laminated timber (CLT) shear wall lateral capacity using stronger connections and a unique coupled wall system with steel links between CLT panels. This project included a major large-scale test to confirm these enhancements.
Ben's research findings from the University of Canterbury are being used in new buildings, especially in New Zealand. This transition from academia to practical application involved collaborations with industry partners like ENGCO, which applied the research on high-capacity connections using mixed-angle screw hold downs in seismic regions, directly integrating these innovative techniques into construction projects.
In New Zealand, when designing new structures with materials like mass timber, they prioritize performance-based design over directly integrating research ...
