Re: Beam Question
Another thing which will cause that rotation is overspanning a beam.
When the beam starts to deflect, it also starts to rotate, the more it deflects, the more it rotates. The more it rotates, the weaker it becomes, the more it deflects.
Self-fulfilling failure, it just becomes a matter of time.
I've also seen some, but as Bruce said, only on high height/width ratio beams. I guess that also could be because smaller beams are loaded less than tall beams, thus the loading on an overspanned beam would have less of that effect.
