Editor’s Note: The purpose of this article series is to identify truss-related structural issues sometimes missed due to the day-in and day-out demands of truss design/production and the fragmented building design review and approval process. This series will explore issues in the building market that are not normally focused upon, and provide recommended best-practice guidance.
The first two Standard of Care articles discussed deferred submittals and truss-to-truss connections. This article explores truss minimum required bearing width issues from the perspective of the design community.
Explore the two different methods used to calculate a wall panel’s capacity to resist applied lateral loads.
- A lot has changed in the components industry over the past two decades, and a new Framing the American Dream (FAD) project would allow us to quantify just how much, as well as detail our product’s benefits over other framing methods.
- Beyond FAD, SBCA is also focusing on helping component manufacturers across the country fight an unfair provision in the model building code, R501.3.
- As you think about investing in the future of your business, think about how much you’re willing to invest this year in these two projects to ensure a bright future for our industry.
- By conducting its own ASTM E119 floor assembly fire testing, SBCA has the data it needs to effectively fight the controversial IRC Section R501.3 code provision and help preserve CMs’ market share.
- SBCA has drafted template best practice language CMs should consider using in their TDDs, customer contracts and submittal documents to counter the efforts of the lumber industry to shift liability onto end users.
- Through Framing the American Dream and WorkForce Development efforts, SBCA is actively engaged in helping CMs successfully navigate today’s labor challenges and grow their businesses.
Truss industry standard of care items are contained throughout ANSI/TPI 1,* The National Standard for Metal Plate Connected Wood Truss Construction. The focus of this article is ANSI/TPI 1 Chapter 2, Section 2.3.5.1 and companion Section 2.4.5.1, which require a truss designer to prepare truss design drawings (TDD) based on design criteria and requirements set forth in the construction documents. The truss industry should expect to get this information from the building designer (BD), which may include the building owner, contractor or a registered design professional (RDP). Particularly when there is an RDP for the building, the design community expects the truss industry to design components that conform to the truss framing plan and specified design parameters within the construction documents, unless instructed otherwise in writing.
