About the event

This regional online technical session examines the practical structural engineering requirements for four- to six-story multi-family wood buildings. The presentation focuses on structural design steps, gravity framing, and lateral analysis. Key engineering subjects include mitigating wood shrinkage effects on components, managing stacked bearing wall loads, and analyzing floor vibration. The session also addresses lateral displacement, diaphragm flexibility, and force transfer mechanisms across multi-story frames. In addition, participants evaluate the structural impacts of fire retardant-treated wood in exterior wall assemblies for Type III construction to ensure robust building performance.

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
