Attic Truss Load Bearing

It most likely is a load bearing wall even without the hvac unit taken in consideration.

Attic truss load bearing.

Go up in the attic and find where the wall you want to remove hits the ceiling. By contrast a non load bearing wall sometimes called a partition wall is responsible only for holding up itself. Most simple construction truss roof home s roof and trusses are supported by the exterior walls perpendicular to the trusses. A load bearing wall is any wall that holds up the weight of the structure above and the people furniture supported by that structure.

The live loads a truss is required to bear are determined by local building codes. You will need an engineer involved in this since many contractors will tell you anything to get the job. We usually build on the exterior walls set the trusses and do all of the chord blocking and truss bracing before buildin. Trusses is cost savings through ease of roof construction.

The double cantilever truss adds height to the structure and contributes to a light and graceful appearance. Two horizontal beams that extend beyond the load they re bearing and are fixed at one end. The floors above roof structure people and furniture are the loads that the wall has to support. They should be designed to span the whole width but they also could have been engineered to have a load bearing wall.

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. Engineered roof truss systems may be designed to eliminate the need for load bearing walls or change where the bearing walls are located. A load bearing wall transfers load all the way down to the building s foundation. Both sides of the equation should be equal in order to end up with a stable and secure roof structure.

Unfortunately my home builder had framed out the attic using a common truss system utilizing 2x4 s see attached picture of exact type although my roof is much steeper and no middle non bearing wall below. You loose the upstairs space. Truss roofs are typically designed to use some interior walls as mid span support to save on costs associated with making the truss larger stronger. If the bottom chord of a roof truss functions as a floor joist such as in an attic room it carries a live load that also varies by use but a typical live floor load for a residential space is about 40 pounds per square foot.

Load bearing walls support the weight of a floor or roof structure above and are so named because they bear a load.
