profileBasedStructuralElementType

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. The profile consists of points and of sheets connecting them. The properties of each sheet are defined in the sheetProperties element, which references the sheet by its uID; pointProperties reference points of the profile. The coordinate system of a sheet, to which the orthotropy direction of a composite refers, and an example are given in the documentation of structuralProfileType.

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.
