Service Conditions and Durable Design for Fasteners in Mass Timber Construction
December 11, 2025 | Thu 12:00 America/Chicago
Duration: 1.0 Hour
CE Credits: 1.0
$300
This presentation explores how service conditions critically impact the performance and durability of fasteners in mass timber construction. Fasteners are a key component in the integrity and lifespan of structures, especially when exposed to varying environmental factors such as moisture, pollution, and corrosive marine environments.
Attendees will gain insights into the different service environments—dry, wet, and waterfront—and their direct effects on fastener connections. The discussion will cover the impact of moisture content on fastener performance, highlighting moisture content adjustment factors both at fabrication and in service. Additionally, we will examine heightened corrosion risks, particularly in chemically treated wood, and explore advanced mitigation strategies, including metal compatibility and protective coatings. A significant focus will be on hydrogen embrittlement and bimetallic contact corrosion, addressing guidelines for preventing these conditions. Practical design considerations will also be shared, emphasizing fastener spacing, installation techniques, and accommodating wood movement.
The presentation will be grounded in real-world case studies, offering lessons learned from successful mass timber projects. Attendees will walk away equipped with knowledge to ensure fastener durability in diverse service conditions, advancing the resilience of mass timber construction.
- Course will award 1.0 hour of continuing education
- Diamond Review approved in all 50 states
- This webinar will be available as a recording.
