About the event

This regional in-person seminar and tour hosted by WoodWorks explores practical structural design considerations for four to six story multi-family wood buildings. The presentation moves beyond baseline code requirements to address gravity framing, shrinkage detailing, floor vibration, stacked bearing wall loads, and lateral analysis including diaphragm flexibility and overturning forces. Following the educational session and lunch, participants tour Montana State University’s School of Computing at Gianforte Hall. The walk-through of the 55,000-square-foot mass timber facility offers an on-site look at hybrid structural systems, detailing, sequencing, and integrated sustainability strategies.

What you’ll learn

  • Discuss wood's shrinkage potential and causes, identify shrinkage effects on structural and non-structural components, and review detailing best practices to minimize the effects of shrinkage
  • Highlight structural implications of utilizing fire retardant-treated wood in exterior wall assemblies of Type III construction.
  • Review floor vibration design checks and associated criteria for residential occupancies in wood-frame construction
  • Explain important lateral engineering issues such as diaphragm flexibility, shear wall configuration options and design, and load path continuity that must be considered to successfully design a mid-rise wood structure.
