Attic Trusses Resting On Non Bearing Wall

It is carrying the weight of the ceiling.

Attic trusses resting on non bearing wall.

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. 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. Chances are this is a non bearing wall. When joists trusses are perpendicular to the wall and bear on the top of the wall that wall is bearing wall.

If the wall in question is parallel to the joists trusses it will likely not be load bearing. The concern is that when the truss deflects the non bearing wall could be an effective support point. The outside walls are supporting the roof so they re bearing walls. Actually a quick way to determine if the wall is bearing is to cut hole at the top to see if it has one or two top plates.

If there is a truss over the wall the wall is probably not load bearing since the truss bears the load. If your roof is trusses no walls internally are load bearing only the external walls are. Non load bearing walls non loadbearing walls must comply with the requirements specified in the relevant standards as appropriate to the material. There may still not be any interior bearing walls but you should check carefully.

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. 3 only part of the roof framing may be trusses and the rest is rafters as in the photo below. Non loadbearing walls as designated shall not carry any truss loading and shall not be packed to touch the underside of trusses see figure below. An example of a load bearing wall call be seen on the right.

An example of a non load bearing partition wall can be seen on the left. If there are two plates refer to an engineer. If the support point is at a truss panel point additional load could be put on the element supporting the non bearing wall thus causing distress. Ceiling joists that meet over the wall indicate that it s a bearing wall.
