Garage Plans

[gdchapma]

Hey Guys,

I am having problems deciding on which direction to go with my garage build. I already have all of the block work done and the floor poured (36’ X 28’). My original plan was to have 10’ ceilings and an upstairs room above that would be about 28’ X 28’ with 8’ ceilings. This plan has changed many times due to the 28’ span of the floor joist. I can’t get a straight answer on the size of a TJI style joist or if I can even use them. One place told me that I could use 11 7/8” joist, another place tells me that I need 16” tall joists, then another place tell me that I cant use these joist, and I need 24” floor trusses. I am so confused now that I am not sure what I will end up doing. I may even change my plan to 12’ ceiling and use attic trusses on top. I want to get back on this thing soon so any advice will be appreciated. If someone will tell me how to post AutoCAD drawings on here I will post some of my plans.

Thanks,
Gary

Do a Save As ---> JPG or PDF

If you unsure how to construct the garage, sometimes it's best to consult an architect familiar with the local codes.

You could use a 28 ft. steel I dropped with 2 x 12 fj's leaving a 16 ft. span. Another solution is to have a ML or a paralam beam sized if the steel has you worried.
I used a 24 foot W10 and a 30 foot W12 in my barn with 3 x 10 floor joists ( true dimension locally cut lumber ) supported with 4 inch square steel columns.
There are many wood I joists and web joists available. Every brand has different specifications they are not all the same. You need to have an architect or engineer size the joist and check state codes for the maximum allowable span. New York now has a 26 max. span under the Residential Code of New York State.

Good luck.

According to my book, Tus joist macmillan, about 4 years old, 14" tji550/pro 16" o.c. if you could get away with L/360 deflection. From your pic it looks like the floor joists and roof would be bearing on the door wall, that would require a beefy header. You would have 4 big point loads in the front wall, is your foundation designed for that? Floor trusses would have to be deeper, 2', but they could be top chord bearing and hang down to save you some building height, I would guess they would be cheaper also as you could space them out a little more.

What version of autocad are you running? Mine has a "publish to web" function, but I have no clue how to use it.

My basic garage started out as 28" deep - I had to use 16"-ers....& there's still some bounce in the 2nd floor.

Thanks for the replies, I really want to have a clear open space in the lower part of the garage, but how much would I really hate having 2 support poles in it? It would solve a lot of problems. With support poles I could use 2x10 lumber and it would be much cheaper. (Probably 3-5k).

I use AutoCAD 2006; you don’t have the option to save as JPG or PDF. I was trying to copy and paste into paint or Photoshop, but they are too large to post, and when I reduce the size they are too small to see. I will figure out something.

Thanks Again.

Cool design,
I'd just go with a couple poles and be done with it. I think any bounce and thoughts in the back of your mind of something breaking would make a couple poles worth it. It's a large space anyway, don't think the poles will take up much visual space (can always wrap in padding to protect from dings etc).
Good luck, and I'm jealous of that large space!!!

I am building a garage, well a house too, and it is 34' deep by 40' wide with two 16' doors on the "deep" side. There is a bonus room up above. There is no poles at all. Just two beefy headers above the garage doors and we are using floor trusses. BTW the trusses are on the 34" span. I have a 12/12 pitch though, so I will lose alot of upstair floor space (loss of 8' at the 8' ceiling hieght) but I will still have 18' of room width to play with.

Take your plans to a truss company and they will set you up right from the get go. Good luck and finish that thing.

Gary, use the command: bmpout
choose a filename and a location to save the file, it will be in .bmp format
bring that .bmp file into Photoshop and use the Save For Web feature to save it as a .jpg

Here is a section view of what I was tossing around in my head. I am also trying out Spencer Was Here's idea. Thanks

Hey it worked, Thanks again, Learn something new everyday.







Here it is attached to my existing house that my wife and I built about 7 years ago. We did most of the work ourselves.

We have the full version of Adobe at work to make PDFs. You actually print to a PDF file, just like any other printer. Just a little FYI.

Full Adobe PDF = $299.

This one give you the print driver for $14.95. http://www.gohtm.com/easypdf/index.htm

I know you can get 11 7/8 TJI up to 42 feet long. I would call the TJI company and have them do a load plan for the span etc. They will do it for free most of the time.

I used steel to get the span I wanted.
