The video opens by highlighting a common scenario in construction: a structural beam supporting an upper floor protrudes beyond the intended lower roofline. These beams are crucial for supporting the weight of the upper floor, and altering them can compromise the structural integrity of the building.
Then cautions viewers about the limitations of cutting these beams. Building codes typically restrict the amount of material that can be removed from a structural beam.
The rule of thumb: only about a quarter of the beam's height can be safely cut at an angle, but stresses that consulting a structural engineer is paramount.
Why You Should Not Cut Beams Until You Have Written Permission From Engineer
This seemingly simple fix can have disastrous consequences.
The beam supports the weight of the upper floor, and cutting it can lead to structural failure.
The consequences of a beam failure can be severe, ranging from damage to the structure to injury to occupants.
The video acknowledges that in rare cases, a structural engineer may approve cutting a beam. In the specific situation shown in the video, the beam was allowed to be cut because of a metal post connector that extended past the beam itself. This particular situation likely strengthened the connection enough to offset the weakness caused by cutting the beam.
Bonus Tip
Take pictures of the beam and surrounding area. Digital pictures can be a valuable tool for the structural engineer to assess the situation.
In conclusion, this is a cautionary tale for homeowners undertaking construction projects. It emphasizes the importance of consulting a structural engineer whenever a structural beam needs modification. By prioritizing safety and seeking professional help, homeowners can avoid costly mistakes and ensure the stability of their homes.
