while I was going through the IFC4 ADD2, I came accross this interesting definition.
IfcColumn is a vertical structural member which often is aligned with a structural grid intersection. It represents a vertical, or nearly vertical, structural member that transmits, through compression, the weight of the structure above to other structural elements below. It represents such a member from an architectural point of view. It is not required to be load bearing.
It is not required to be load bearing???
All of the three first sentences described this element as a structural column that carries loads. So how can this column not be load bearing?
Well, in my 15 years experience…I have never build a structural column that transmits weight and was not load bearing at the same time. If it is non load bearing, that mean it is also non structural. Am I missing something here?
