In this post, the last in a series of six, we will discuss how to build code-compliant stairs for your deck. When constructing a deck, ensuring that stair stringers and treads are properly connected is crucial for safety and compliance with building codes. Here are some key considerations for stair dimensions and connections:

Decks Done Right Series — Real Solutions for Safer, Stronger Decks: Joists, Joist Connections, Beams, and Lateral Requirements
Deck Beams and Joists
Deck beams and joists need to be sized, spaced, and supported properly to support the loads that they are subjected to. The tables in 2021 IRC R507.5 list maximum beam spans for the different wood species members based on various ground snow loads. Table R507.6 helps to determine the maximum joist span, considering live load, wood species, joist spacing, joist size, and whether there’s a cantilever or not. Cantilevers are included but are maxed out at L/4. Joist spacing should be no more than 16″ o/c for decking that runs perpendicular to joists and no more than 12″ o.c. if the decking runs diagonal to them. DCA 6, Table 2 is the comparable section that addresses maximum joist spans and overhangs. These member sizes and spans are developed using established code minimum distributed loads of 40 psf live and 10 psf dead.

24th Short Course on CFS Structures: October 27-29 in St. Louis
Simpson Strong-Tie is sponsoring the 24th Short Course on Cold-Formed Steel Structures hosted by the Wei-Wen Yu Center for Cold-Formed Steel Structures (CCFSS). The course will be held on October 27-29, 2015 at the Drury Plaza Hotel at the Arch in St. Louis, MO.
This three-day course is for engineers who have limited or no experience designing with cold-formed steel (CFS), as well as those with experience who would like to expand their knowledge of cold-formed steel structural design. Lectures will be given by industry-recognized experts Roger LaBoube, Ph.D., P.E., and Sutton Stephens, Ph.D., P.E., S.E. The course is based on the 2012 AISI North American Specification for the Design of Cold-Formed Steel Structural Members and the 2012 North American Standards for Cold-Formed Steel Framing. Dr. Wei-Wen Yu’s book Cold-Formed Steel Design (4th Edition) will be a reference text.
The course will address such topics as design of wall studs, floor joists, purlins, girts, decks and panels. It is eligible for 2.4 Continuing Education Units (CEUs). Advance registration is requested by October 10, 2015. For more information and to register, click here.
