Eccentricity in shell elements

In Revit user can decide about the position of Analytical Wall and Analytical Floor / Analytical Foundation Slab in relation to the physical model. Those settings are exported to FEM-Design as Eccentricity and the Alignment is set to one of the three values: Top/Left, Center or Bottom/Right. Example of an alignment setting in case of floor element.

Analytical floor

Following Analytical Alignment definition of an Analytical Floor / Analytical Foundation Slab is exported to FEM-Design.

Alignment method:

  • Projection

z Projection:

  • Top of Slab
  • Center of Slab
  • Bottom of Slab

In any other case, i.e. Projection is set to a Level or a Reference Plane, or the Alignment Method is set to be Auto detect, the default position of Analytical Floor / Analytical Foundation Slab in relation to physical element after export to FEM-Design will be: Center.

Example

Example of different settings in Revit and the final result after opening the exported model in FEM-Design is shown in table below.

Analytical wall

Following Analytical Alignment settings of an Analytical Wall are exported to FEM-Design:

Alignment method:

  • Projection

z Projection:

  • Center of element
  • Interior Face
  • Center of Core
  • Exterior Face

In any other case, i.e. Projection is set to a Grid or a Reference Plane or the Alignment Method is set to be Auto detect, the default position of analytical model in relation to physical element after export to FEM-Design will be: Center.

Example of different settings in Revit and the final result after opening the exported model in FEM-Design is shown in table below.

Eccentricity in beams

Almost any configuration of analytical beam model in regards to its physical representation can be transferred to struxml and read in FEM-Design as Eccentricity. In order to export physical eccentricity in beams, one has to check the Export beam eccentricity box in the Export StruXML dialog.
