Load Bearing or Not?

I just bought a house that was built in 1973; I want to open up the living and dining area, and the wall I wish to remove runs down the center full length of the house. The roof system is factory made trusses; there is no header above the doors. The walls were prefabricated off site and set into place as units shored up with 1x4, there are no king studs, there is a double sill plate but I think this is just to shore up the prefabricated walls. I do have pictures available if anyone would like to see I could email them.

Welcome to the forums

Normally the only load bearing walls with trusses are at the two opposing ends of the truss.

After reviewing the pictures, my opinion is that the trusses are supported on the exterior walls only as marksr mentioned. You have a simple Fink truss which places load at the ends. However, due to the 12 lf span between the bottom V of the web, we need to ensure that no sagging would take place due to the 2x4 bottom chord and drywall weight.

I suggest, BEFORE REMOVING THE WALL, the following options, your choice,

1. Install a horizontal collar tie 2 feet down from the diagonals, this can be 1x4/6 or 2x stock and then install a vertical member of 1x4 or 2x from this down to the 2x4 bottom chord.

2. Install a vertical member only of 1x6 from peak of the truss down to the 2x4 bottom chord.

Since it appears that we do not have a load directly on the wall that you intend to remove, the span may create a slight sag which we do not want. The above options would ensure this.

Hope this helps!
