Structural elements based on profiles
Name of the profile based structural element
Description of the profile based structural element
Choice between global beam properties and sheet properties
Definition of the properties of the structural profile sheet
Choice between general profile element description (referencing a structuralProfile) and predefined standard profiles
Definition based on structuralProfile definition
Reference to the structural profile profile uID
Reference point in structural profile definition for structural element definition
Standard Profile Type, see picture below for further information.
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:
In the section globalBeamProperties the properties of the structural profile in an equivalent beam representation are defined.
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.:
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.
