Short description

The ProfileBasedStructuralElement type containins the data of a structural element, that are based on 2-dimensional profiles.

There are three approaches to model profile based structural elements:

  • by specifying global beam properties
  • by referencing a structuralProfile2D element
  • by choosing one of the prescribed standard profiles

1. Global beam properties

In the section globalBeamProperties the properties of the structural profile in an equivalent beam representation are defined.

2. Structural 2D profile

The structuralProfileUID element refers to the uID of the structuralProfile2D element. As described in the corresponding documentation, this profile is defined by several points in the x-y-space. Two points always form a sheet. The properties of each sheet are defined in the sheetProperties element. The orthotropy direction of composite materials equals the sheets' x-axis. The orthotropy direction angle equals a positive rotation around the sheets' z-axis as indicated in the picture below (part 3), which shows an example of a wing stringer.:

3. Standard structural 2D profile

Instead of referencing a structuralProfile2D element, it is also possible to select a predefined standard profile. These profiles are listed in the figure below. Under sheetProperties, only the standardProfileSheetID (equals S1, S2, ...) must now be specified along with a corresponding length.
