Learn about managing wood moisture content, fastener tension, and new CSA O86:24 provisions in dynamic construction environments.

The construction environment is a dynamic weather and exposure environment that can range from dry to cold and wet to dry. Wood materials are in a constant state of moisture content change with the environment that affects dimensional change, corrosion activity, fungi and decay, and the tension of embedded screws. The presentation includes some of the new provisions of CSA O86:24 related to mass timber screws and the Simpson Strong-Tie R&D work to understand and mitigate HE as affected by hardness, manufacturing, and use environments.

Credits: Participants will earn one professional development hour (PDH). After completing the post-webinar online quiz, you can earn 0.1 continuing education unit (CEU) as well.

Attendee Prerequisites: Some experience in this field is helpful.

Intended Audience: Structural engineers, specifiers, architects, building officials, residential & commercial contractors, home owners and DIYers.

We’ll have a live Q&A at the end.

Learning Objectives:

• Identify the importance of managing the construction environment surrounding fasteners driven through thick steel plates into wood.
• Describe the effect of wood moisture content on the tension of threaded fasteners embedded in wood.
• Explain how to prevent HE failures in the construction environment.
• Summarize the provisions of CSA O86:24 related to mass timber fastening.
• Incorporate installation provisions for mass timber fasteners driven through thick metal plates into wood.
