Intro to Repetitive Light-Frame Wood Roof Framing
James B. Smith, P.E.
Intuitive Codes and Consulting
Course Description
This presentation will introduce basic engineering principles applicable to light-frame wood construction using both solid sawn lumber and Engineered Wood Products commonly used in the Mid-Atlantic and New England regions. We will discuss the critical concept of load path and how the roof framing system safely transfers lateral load from high wind events through the structural framing system. Best framing practices, Wood Structural Panels (WSP’s), the importance of fasteners, and the continuity of connections will be discussed. Design for Code Acceptance 6 (DCA6)-15 Prescriptive Residential Wood Deck Guide, with 2018 IRC Updates Course Description: Hundreds of wood decks get built every year and some without the proper guidance for designing or constructing a safe deck. However, AWC DCA6-15, which is in the process of being updated, includes guidance on provisions for the 2015 & 2018 International Residential Code (IRC) pertaining to single level residential wood deck construction. Provisions contained in this document that are not included in the IRC are considered good practice. When you get the question “why doesn’t the DCA6 document line up with the 2021 IRC?”, there are a number of reasons. One at the forefront is that the IRC only addresses axial loading of the supporting posts. They do not address bending forces that the DCA6 does. There are some other issues such as span length (the I-Codes measure from the center of the framing member-difficult to fi eld verify, and DCA6 measures from face of member to the contact point of the supporting member). In short, DCA6 is a more conservative document than the IRC. Finally, the standard nailed post base connections have no resistance to lateral loads. They essentially function as a pin connection from a structural engineering standpoint. There are some proprietary post base connections that do provide moment resistance for those loads, but they are very expensive, and they require a very robust reinforcing steel package in the footing. Just some food for thought when you get into Decks in the IRC.
