About the event

This regional in-person seminar and tour offers structural engineers practical guidance for designing four- to six-story multi-family wood buildings. The session examines structural design steps and detailing best practices across both gravity and lateral systems. Key topics include shrinkage mitigation, diaphragm flexibility, shear wall load paths, stacked bearing wall loads, and floor vibration checks. The presentation also addresses structural aspects of fire-retardant-treated wood in Type III construction. Participants then tour Gianforte Hall, a newly opened 55,000-square-foot mass timber facility at Montana State University, exploring hybrid systems and construction sequencing.

What you’ll learn

  • Discuss wood 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
