Question

16' support beam ?


I am looking to remove half my load bearing interior wall on my main floor to open up my kitchen. I was wondering if three 2"x10"by 16' would be enough support for that size opening. It is a 2 storey home.
Thanks,

You need to have the beam sized for the load
You can't guess at this
For a 13' 6" opening I needed either (3) 12" LVL's or (2) 14" LVL's
The (2) 14's were less $$ & stronger
The lumber yard (not big box) sized the beams & they would have sent the plans out for an engineer stamp if I needed one

Thanks,
James, the safest thing for you to do would be to talk with your local building inspector. You will be requiring a permit for this work anyway, and since they will be the people approving your permit, it is best to make sure they are happy.

3 2 x 10's falls somewhat short for that span. If you pick up a copy of the CHMC building specs, you will find the information in there. Your local office may have a copy for sale, or I believe you can order one online directly.

If you plan on doing more work of this nature, it is well worth having.

James, don't forget to look down too. You're looking for a 16' opening (well, a bit less than 16'), but what's under those end points? Are you on top of a window in the basement for instance? Your 16' may be 18 or 19 by the time you find solid ground.

Look into engineered wood beams. http://bct.eco.umass.edu/publication...s-and-headers/

Not sure if the site link is worth anything to you but may point you in the right direction for your search for info.

Also, steel is always an option.
I did a patio enclosure with 3 sets of sliding glass doors all together and we had to use something like a 22' beam. We used a steel I-beam. We used lots of liquid nail to put 2x2 cripples into the openings of the beam to screw drywall too.

Some permit offices will help you
But most will tell you to hire en engineer to have the load calc'd
If they assist you & tell you what to do they are then liable if something goes wrong
They are there in most cases to inspect the work, not tell you how to build it

I did have to add support down to the foundation in the basement for the beam support
In my case it was less then 12"

16' support beam ?


Thanks guys. Sounds like great advise. We are just in the planning stage of options for our kitchen reno. We were going to replace the ceramic tile floor with hardwood, but we thought while we are doing that we may want to take the time to remodel. Armed with this info I think I may just put new flooring down. If this was a home that we were thinking about staying in I would consider a complete reno, but seeing we will be downsizing in 2 or 3 years it seems like a large undertaking at this point. Think I will go break the news to my wife.

Thanks again for your input.

For the record I am going to blame you guys for her not getting a window seat in the kitchen now, sorry, lol.
