This video shows two options of absolute offset and relative offset for creating member eccentricities. It explains the influence of eccentricity on the resulting internal forces.

The beam is resting on the column, and the beam ends at the outer edge of the column. These requirements can be fulfilled easily in an architectural model with solids. In member analysis, simplified line models are used in which center lines meet in a common node. In this article, the influence of member eccentricities on the determination of internal forces is shown on three simple models.
In the case of a parallel offset of the structural plane of members and surfaces and also applying an axial offset to members, for example, the function of eccentricities may be useful.
When modeling eccentric members with member hinges, RFEM provides the option to assign the hinge to the start or end of the member eccentricity. There is another option for creating and displaying the structural system more precisely in the design.
For structural reasons, it may be necessary for a base plate not to be set centrically on a foundation. Therefore, an eccentric arrangement of the base plate is possible in RF‑/JOINTS Steel - Column Base by entering the parameters for the respective direction in Window 1.4.
Use the "Independent mesh preferred" option in the FE mesh settings to create an independent FE mesh for the integrated objects. This allows you to generate a significantly more detailed and precise FE mesh for individual objects that are integrated into one another.
In the "Edit Section" dialog box, you can display the buckling shapes of the Finite Strip Method (FSM) as a 3D graphic.
In RFEM 6 and RSTAB 9, you have the option to enter "Visual Objects" as guide objects. You can import the file formats 3ds, stl, and obj.
These objects allow you to create a better reference to the dimensions.
Do you have individual column sections and angled wall geometries, and need punching shear design for them?
No problem. In RFEM 6, you can perform punching shear design not only for rectangular and circular sections, but for any cross-section shape.
How can I assign a common eccentricity to several different cross-sections at once?
Does RFEM recognize that a member is connected to a surface despite the eccentricity?
Why does an eccentric member receive axial forces, although it is only loaded by shear forces?
How can I create member eccentricities in RS‑COM?
Why is it not possible to define eccentricity in the Z‑direction in my 2D model?
In RSTAB, how can I select the side of eccentrically connected members on which the hinge is effective?
