C7. Offsets 

C7. Offsets 

Most finite element software offer several options to define a beam on a fiber other than its neutral fiber.

This option is very useful, for example:

However, it is necessary to define the offset between this defining fiber and the neutral fiber, this offset being the eccentricity that can vary along the beam.

In case of doubt about the operation of this option, you can check it with another model where each beam is defined at its neutral fiber by creating the offset yourself with rigid links.

The subject of offsets is partially illustrated in the document Example of Prestressing and Offsets.
