Diamond-built 0 Posted April 27, 2016 I am drawing a 26 x 28 garage. The client is asking for a 2 x 10 clear span ceiling joist with a strong back on top of them. What is he asking for a Steel I beam? Share this post Link to post Share on other sites
Gawdzira 214 Posted April 27, 2016 Is your client an engineer? Your question, and the design of long span structural elements are why we have structural engineers. Share this post Link to post Share on other sites

joey_martin 364 Posted April 27, 2016 This is what he asking for. I would, in return, ask him for a waiver of liability when the sag becomes so bad that his ceiling fails. I would have to double check...but I am not even sure a 9 1/4" I-Joist would span that. *Why are trusses not an option? Share this post Link to post Share on other sites

Gawdzira 214 Posted April 27, 2016 Joey, I think you are on the wrong chart. I suspect the reason for avoiding trusses (which would probably be a cheaper and easier to build with) is that this "loft" area is going to be used for storage. Therefore, the floor joist table would be more appropriate. Share this post Link to post Share on other sites
Diamond-built 0 Posted April 27, 2016 No loft above from what I've been told. Share this post Link to post Share on other sites
dshall 1494 Posted April 27, 2016 ......is that this "loft" area is going to be used for storage. ..... Alan, that space above the ceiling joists, especially where there is a wide span, hence a high ridge, is never used for storage......... it is usually used for an unpermitted second floor. Just goofing guys, it's early in the morning, a little humor to start the day. Share this post Link to post Share on other sites
joey_martin 364 Posted April 27, 2016 I didn't see mention of loft, but I know that a 2"x10" wouldn't work with any sort of storage or livable space at that span, so I went with the ceiling joist chart. Share this post Link to post Share on other sites
javatom 131 Posted April 27, 2016 He is a framer so naturally, he will do it how he wants no matter what you put on the plans. Share this post Link to post Share on other sites

Diamond-built 0 Posted April 28, 2016 Now knowing what I need 2 x 10 clear span ceiling joist with a strong back how do I draw this in? Could someone help me out? Share this post Link to post Share on other sites
joey_martin 364 Posted April 28, 2016 Once you have the ceiling joists set in place, simply place a general framing member on top of them by setting the correct height, then add another and rotate it. You could, if need be, add a couple CAD lines with a note and detail call out and simply make a detail of the needed connection. It's a fairly painless process though.
