The reference to joists here is specifically bar joists, and we add them just like we add w-flange beams...with one exception. The joist seats give us a 2.5" problem. In this video we will be adding angle web K series bar joists to our roof. But we must first set our bearing beams 2.5" down for the joist seat to rest on.

- [Voiceover] What I'd like to do in this video…is add some bar joists to our roof.…The problem is bar joists…have a two and a half inch seat,…so we're gonna have to adjust our framing…to accommodate for that.…Under projects, let's click Open.…Let's find our joist model and click Open.…Let's go up to our roof level.…This looks pretty bare,…so let's label everything.…If you go to the Annotate tab,…and go to Tag All,…let's scroll down and find Structural Framing Tags,…let's click Apply,…let's click Okay.…
Ah ha, that looks a lot better.…Let's put some joists in.…Let's determine which way…we're gonna run our joist first.…Since we have perfect 25 foot bays,…it doesn't really matter,…but let's run our joist vertical.…That means that every beam that a joist bears on…has to be down two and a half inches.…What I'm gonna do is I'm gonna hit my Control key,…and I'm gonna start picking…all of my horizontal beams.…
Now, my start level offset and my end level offset…both need to be down 2.5 inches,…so I'm gonna click in here…I'm gonna type in -2.5 inches.…
