If there is a column that supports the truss found in the wall the wall still would not be load bearing because the column is taking the load.
Load bearing roof truss.
In structure with truss design in the properties dialog box select roof floor bearing options and after you change to yes in is unique to truss in general section click on the drop down menu of bearing design options.
As we will see below there are several different types of designs and this will impact the angles and designs of the overall truss.
Roof trusses support a roof s weight by transferring the weight load downward and outward to the building s bearing walls.
I would think that any wall with a truss over it is not likely to be load bearing.
Engineered roof truss systems may be designed to eliminate the need for load bearing walls or change where the bearing walls are located.
It s often used in high rise buildings such as exposition buildings and grand stands.
Two horizontal beams that extend beyond the load they re bearing and are fixed at one end.
To achieve maximum indicated spans trusses may require six or more panels.
These options include upgrading lumber using a bearing block or using a truss bearing enhancer.
If the number of members is labeled m and the number of nodes is labeled n this can be written as m 3 2 n.
You will need an engineer involved in this since many contractors will tell you anything to get the job.
They do this by means of top chords which are sloping members that extend from the peak of the roof to the top of the exterior walls at the eaves.
Trusses must be designed for any special loading such as concentrated loads from hanging partitions or air conditioning units and snow loads caused by driftingnearparapetorslide offfromhigherroofs.
For example a gable end truss may be designed with support members that transmit the roof weight load outward to the side walls allowing the end wall directly below it to have breaks or openings in it that would otherwise be impossible.
The formula for truss loads states that the number of truss members plus three must equal the twice the number of nodes.
It most likely is a load bearing wall even without the hvac unit taken in consideration.
If there is a truss over the wall the wall is probably not load bearing since the truss bears the load.
The truss is a framework consisting of rafters posts and struts which supports your roof.
