This presentation from the first US CLT Symposium Engineer Eric Karsh walks through advanced engineering concepts in solid wood construction. Karsh explains how solid wood construction is a different building system compared to the past stick frame construction. Solid wood construction’s structure behaves differently from both a design and engineering standpoint. The presentation highlights recent projects using solid wood construction, as the method continues to emerge as a growing trend in the industry.
