PHRC Workshop

PCCA Workshop - IRC 105: Residential Deck Design & Construction

In this half-day, virtual workshop, we will review the current code requirements for residential deck design and construction. This will begin by reviewing multiple deck failures to gain an understanding as to why the codes are written how they are. We will then review the 2015 IRC prescriptive design requirements for joists, beams and post sizing. We will also review the design requirements for stairs and stair illumination. The newly adopted code requirements lay the groundwork for the design of a residential deck. Upon completion, attendees will know where to find and apply the prescriptive design guidelines set forth in the IRC code books.

After attending this program, attendees will be able to:
