Interior Load Bearing Wall Under W Truss Roof

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.

Interior load bearing wall under w truss roof.

But there are five possible exceptions to look out for. With your trusses spanning the exterior walls for the full run of the house no interior walls will be load bearing the splices on trusses are engineered to be self supportive according to the plate sizing the fact that they land over an interior wall has nothing to do with that wall being load bearing trusses are engineered to span exterior wall to exterior wall self supporting. Residentiall roof trusses are designed to bear only on the exterior walls at each end of the span. But if the wall runs perpendicular at a 90 degree angle to the joists there is a good chance that it is load bearing.

If there is a truss over the wall the wall is probably not load bearing since the truss bears the load. It most likely is a load bearing wall even without the hvac unit taken in consideration. In this roof design the exterior walls on which the roof s sloping rafters rest are load bearing walls. But even in that situation there is usually a doubled or tripled up truss at the intersection instead of an interior bearing wall that provides bearing along the bottom chord where the.

Generally when the wall in question runs parallel to the floor joists above it is not a load bearing wall. It is carrying the weight of the ceiling. However if the interior wall was framed before the trusses were set it is possible that the wall prevented deflection of the trusses from the dead load of the trusses sheathing roofing. 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.

I ve never seen a 30 truss that needed intermediate bearing but i can t say that it has never happened. 1 when the home has an l or t shape there may be an interior bearing wall under the intersection of the perpendicular rows of trusses. The outside walls are supporting the roof so they re bearing walls. If one of the truss webs doesn t come down on the wall then it s not load bearing.

In that case some additional deflection after removing the interior wall is possible. However there are cases where a bearing wall is parallel to the joists. A beam directly under a wall usually means that it s a bearing wall whether the beam is in a crawl space basement or on the main floor. You will need an engineer involved in this since many contractors will tell you anything to get the job.

Although they don t bear the full weight load of the roof the gable end walls are also typically load bearing and an interior wall running parallel to the roof ridge in the center of the building often bears a load from the ridge. Interior walls might be load bearing or may not be.
