Prebuilt trusses


Iíd like to remove an interior wall and Iím trying to determine if the wall is load bearing. Iíve been told by some carpenters that since I have prebuilt trusses, only the outside walls are load bearing. Others have said thatís not necessarily so and my little bit of google research has not made it any clearer.

Iíve been a painting contractor for the last 35+ years so Iíve been around construction most of my life. Iíve gained a little knowledge of some of the other trades but Iíll readily admit I know next to nothing about framing.

Hopefully my pics will attach to my post and be helpful. The trusses span approximately 28í all the way down the length of the house (70í). The house is 46 years old.

Any advice or opinions are appreciated.

Re: Prebuilt trusses


You don't have any load bearing walls in there.

The safe bet is just finding a picture of the truss you have, yours look to be Howe girder
I have never found pictures on line that indicate three or four bearing points.

Thanks, Neal. Yes, the Howe girder looks exactly like what I have.

See my post 6, I don't believe you have a problem but this might be a question for a truss company. they would consider the length the pitch and the snow load for your area.

I remember finding one during my google search that looked like mine that was called a ďtri-bearing ď truss.
Hence the confusion.

Anytime we get multi bearing trusses the extra wall will be right in line with one of the uprights, The would not put any load in between the uprights in the truss.

Snow isnít a factor here in the sunny South. How would the pitch affect it it?

The more the snow load the higher the pitch would be.

The wall being considered for removal is offset 2í from center. And in the garage the storage room wall is offset 7í from center. Same type trusses all the length of the house.

Unless all of them are supported under one of the uprights, they would not have trusses and tri bearing in the same row for no reason. I think you are good to go with the big hammer.

Thanks again, Neal. I helped a friend and his carpenter take out a bearing wall about 25í long last Saturday. He had to put in some ďLVLĒ beams (?).

Man, what a process! If I can avoid that Iíll count my lucky stars.

Re: Prebuilt trusses


And as a bonus here, if I post 7 more times Iíll regain access to the CBR.

When they upped the post requirement to 100, I got locked out. I never posted much there but I kinda enjoyed reading the spirited debate.
