A beam-bearing wall is an interior or exterior wall that supports the beam layer of a floor or roof. It is a load-bearing wall that must not be removed without proper structural measures.
Function and application
In traditional building construction, timber or steel floor beams rest on walls. The wall on which these beams bear is called a beam-bearing wall. This wall carries not only the weight of the floor itself, but also all loads acting on that floor, such as furniture, occupants, and any structures above.
Beam-bearing walls appear as external walls (facades) and as internal walls (partition walls that also serve a structural function).
Identification
Identifying a beam-bearing wall is essential before carrying out any renovation work. Typical characteristics include:
- The wall generally runs at right angles to the direction of the floor beams.
- The beam ends rest in or on the wall.
- The wall often continues through multiple storeys.
- On construction drawings, the wall is marked as a load-bearing wall.
Removal or alteration
A beam-bearing wall must never be removed without structural provisions. When creating an opening or demolishing the wall, an alternative load-bearing structure must be installed, such as:
- A steel or concrete girder that takes over the beam loads.
- Columns on either side of the opening to support the girder.
- A truss or portal frame for larger spans.
Always consult a structural engineer before modifying a beam-bearing wall.
