In under a minute of looking at the IRC deck beam design table, you’ll probably think you have it all figured out, but you’d likely be wrong. The footnotes in the 2021 edition give you clues that there is much more to it, but don’t let the fine print fool you. There are some huge implications to them, and ones designers and builders should want to hear. They apply the same to the 2018 edition…but that edition failed to mention them. As with all prescriptive design, there are load and design assumptions that limit the design choices provided. However, with an understanding of what’s happening behind the scenes, building authorities can gain comfort in using a few tricks to maximize the use of the code for prescriptive design for their communities. In this 90-minute live webinar with Glenn Mathewson of Building Code College, you’ll learn all the details about sizing deck beams under the 2018 and 2021 IRC.
Objectives: Upon completion of this course, attendees will
- Understand the load assumptions used to derive the maximum beam spans and adjustments the 2021 IRC allows.
- Learn how to use the IRC in an alternative manner to design beams loaded from both sides.
- Understand the difficulty of providing pre-engineered beam design in the IRC due to variables in the load path.
- Realize the IRC provides methods to fine tune prescriptive design.
