Is this a Load-Bearing wall? Help!
 
6 Attachment(s)
Hey Everyone,

I am a total amateur when it comes to construction. I apologize if some of my terms are incorrect, but I have attached photographs of the original blueprints of the home, and also pictures of what I am talking about.

I just purchased a home, and I am in the process of redoing the basement. I am looking to tear down a wall that is underneath the main beam in the basement. There are three 4" lally columns holding up the beam. There is also the wood that is connected to the beam, which also holds up the drywall.
My question is, are the wood planks also a load-bearing wall?

I would really appreciate it if someone could help me answer the question, can I tear down all the wood, and just keep the lally columns?

If there is anymore information needed, please post!

Thank you very much!

Excellent job with your posting, but an accurate answer is impossible to give, IMO. PROBABLY the posts are enough, since it does not appear that you have a "footer" all along that wall to support what the wall bears, but I would not bet on it without the original engineer on my team.

Thank you jklingel! I appreciate your speedy response, I will look into that.

Anyone else have ideas/facts/opinions? :wink:

Get somebody in there that knows, it is the ONLY way.

The framing (veritical wall studs) underneath the main carrying beam are not load bearing.

However, the triple 2x10 or 2x12 beam itself and the lally column(s) = are most definitely load bearing.

Although you would need to get an SE on site to check, I would say it is highly unlikely that the studwork is structural.
Looking at the plan, each 93" span of the beam is supporting about 100 sq ft of flooring. Assuming a total loading of 50 lbs/sq ft (though code may differ) the bending stress in the beam would be well within limits, particularly if the timbers are continuous over the spans, and well-spliced.
(This is assuming it is an open floor above with no walls or partitions etc contributing additional loads to the beam)
I would say it is worth the money getting an SE in to check and confirm this.

I plan on re-doing my unfinished basement in a typical 1960's colonial house with platform framing. The main beam in the basement is a tripled 2x10" with lally columns that are about 90" apart.

I had a structural engineer come out and verify that my studs attached to the beam were for non load bearing (for drywall installation only) but that concrete filled lally columns were indeed load bearing.

But your situation may be different, so I highly suggest you get a licensed SE for review.

It cost me 300 bucks for his review and an official report but when it comes to something like this, peace of mind is priceless.

Well said!

I suggest a S.E. also. Your plans show a 6x10 for the main beam, I presume a two story house for that size timber. The builder substituted 3/2x10's instead, perhaps the frame inspection caught it and required studding below.

6x10 = 1800# per lin.ft.

3/2x10's = 1400# per lin.ft. Quite the difference, ask a local engineer for your snow/roof/story loads.
