A Load Bearing Wall Can Be Deceptive

By Tim Carter
©1993-2008 Tim Carter
Summary: Your walls can fool you. Posing as an innocent non-load bearing wall, an interior wall may, in fact, be a prime load bearing wall. Check this photo.

 

An Innocent Looking Wall

Here is an interior wall of my own home. Sorry about all of the clutter. As I took the photo, I was standing in the family room looking at the breakfast table and the adjacent window on the outside wall.

This load bearing wall has a large opening and a doorway. PHOTO CREDIT: Tim Carter
The average person would think the interior wall with the large opening and doorway is a standard interior non-load bearing wall. The truth is, that this wall has an enormous load upon it. Directly above the wall is a wall that supports part of the roof of my home. In addition, there is a major beam hidden in the ceiling that runs just above and a little behind the crown molding that you see in the upper left corner of the photograph. This beam carries one entire side of the roof, and one third of the second and third floor loads! The beam rests on a column within the wall about one foot to the left of the large pass-through opening. Above the large pass through and the doorway are triple 2 x 12 beams.

The point is, that there are large concentrated loads at the edges of these two openings. Beneath the floor, I placed blocking that transmits these loads directly to a 12 inch deep 12x31 I beam, that I work directly underneath each and every day.

Dear sir, Iam a very disabled person. I have a question and I can't get even close to what I need to know useing the net! I need to build a retaining wall( Block is th cheapest?)and then I want to attach it to the house with a deck nailed to the wall. The deck joists attached to the house foundation buy pouring a footing and j bolting a timber on top of that for the joists to attach to.Then there is an old deck above that that needs to be replaced. Eventully I would like to enclose that area, Im basicly bed bound and I need this area to be able to roll to to get outr of my dark drury Dungin.The deck would be approx. 15x22 the 22feet is inline with my home. The deck would go out approx. 15 feet from my home. The wall or top of grade is about 5 and a half feet tall in order to line up with the basement door.The wall would be approx. 4and a half feet tall and about 50 feet long. I can't seem to find anything to help show to me how to build the wall. I have limited funds but, I found a gov. agency to loan me 25 Grand.Would appreciate any help or ideas.Sincerely yours RGH Sr.

Ron,
You need to talk with some remodeling contractors. The reason you can't find what you need on the Internet is that there are many variables that are job specific to *your* home. I would also see if there are some local social agencies that assist in matchmaking in situations like this. You can't possibly be the first challenged person is your area who has needed remodeling work performed.

Talleon,
By building a temporary bearing wall or installing a beam in place of the wall. You better get a structural engineer on your team before you get in over your head.

Hello....I am remodeling my kitchen and have to remove part of a load bearing wall. I need to span 8'. This is 2 story home with a basement. My question is...do I have to transfer the weight directly below my jack studs to the basement floor. I have a
beam that spans the entire length of the basement for the upstairs load. And will 2 (two) 2x8 be sufficient for the 8' span? Please let me know...
thanks rich

Rich,
I can't answer because you might have left out critical data. Read all of my bearing-walls columns and you will see the monsters that can be in the walls. Read about the wall between my family and breakfast rooms.

Debbie,
You need to read all of my columns about Bearing Walls. Then follow my advice in them, or roll the dice if you are a gambler..... :->
