2 docs tagged with "reference point"

Typically models are built with beam elements connecting at nodes, but this implies an overlap as it ignores the dimensions of the elements modelled as lines.

The reference point is the point where axial loads on a section are assumed to apply. By default this is the centroid, meaning that an axial loads produces no bending. However in some situations it is better to assume loads are applied with an eccentricity. One way to achieve this is to apply an offset to the section.
