Until recently, 4×4 posts were used to support decks with little thought to how much they carried or how tall they were. The 2015 IRC shocked many with a maximum 8-foot 4×4 post height, and the 2018 IRC continued the chaos with a limit that appeared to be even lower. Finally, in the 2021 edition, the post sizing table is all grown up and ready to accurately size deck support posts based on the deck design. Other new provisions have also been added to the 2021 IRC for post connections, but they aren’t as precise as the code so specifically presents them to be. In this 90-minute webinar with deck code expert Glenn Mathewson, you’ll learn the details and the design behind the new post provisions in the 2021 IRC. Upon completion of this course, attendees will:
- Understand the evolution of the post sizing table from the 2015 IRC to the 2021 IRC.
- Be comfortable utilizing and approving the 2021 IRC for post sizing as an alternative to previous editions.
- Realize how the 2021 IRC can be used to size posts for two-level decks and porch roofs.
- Discover the reality behind the specific post-to-beam provisions in the IRC.
