Course Description

This session examines advanced design and construction topics that influence the performance of mass timber buildings, with an emphasis on connection detailing, fabrication considerations, and long-term behavior. Through research insights and built case study examples, presenters will address fire and seismic design implications for Type IV construction, deformation compatibility, and durability considerations related to moisture and fastener performance. Attendees will gain practical insights to support code-compliant design, improve constructability, and enhance the resilience and reliability of mass timber structures.

Learning Objectives

1. Evaluate advanced structural systems for mass timber and hybrid buildings, including timber–concrete composite floors, post-tensioned timber, and integrated wood–steel–concrete assemblies.
2. Incorporate field data and experimental insights to improve serviceability, occupant comfort, and long-term reliability of mass timber floor and structural systems.
3. Assess connection detailing strategies that balance structural performance, constructability, and architectural intent in complex hybrid projects.
4. Apply performance-based seismic design concepts to mass timber lateral force-resisting systems, including the role of ductile components and confinement detailing, ensuring structural safety and resiliency.
