StructuralCrossSection

Cross-section

A cross-section together with material (StructuralMaterial) is a basic property of a 1D member. Various kinds of shapes can be defined, including steel rolled sections, timber specific cross-sections or general geometric sections. Supported shapes of cross-sections are defined in documents Formcodes and Description ID of the profile, in chapter Annexes in this document.

Specification in excel

Column header	Data type	Example / enum definition	Required	Description
Name	String	CS1	yes	Human readable unique name of the Cross-section
Material	String	MAT1	yes	Name reference to the existing StructuralMaterial object. The general type of cross-section can have more than one material. Each material name is separated by a semicolon.
Cross-section type	Enum	Parametric Manufactured Compound General	yes	Define the type of profile library: General: Serves to define any general shape of the cross-section consisting of one or more closed polygons including openings. Shape of the cross-section (polygons) is defined on separate sheet “CompositeShapeDef” Parametric: Cross-sections defined by shape and dimensions (parameters). Manufactured: This option refers to the industrially manufactured cross-sections. Compound: prepared for compounded section fom more manufactured profiles e.g. for two I-sections. Example of compound cross-section input: profile = IPE200 and parameters=10mm (distance between profiles). All supported shapes of compound section can be found in Annex
Shape	Enum	T Section	yes, if Cross-section type = Parametric yes, if Cross-section type = Compound	This field defines geometrical shape of the cross-section, is required only if Cross-section type is not manufactured. Complete list of supported shapes is attached in Supported shapes of cross-section.
Parameters [mm]	String	50; 80; 500; 450	yes, if Cross-section type = Parametric yes, if Cross-section type = Compound	The format of the parameters depends on cross section shape, described in the Annexes: Supported shapes of parametric cross-sections Supported shapes of compound cross-sections Each parameter has to be divided by a semicolon.
Profile	String	HEB180	yes, if Cross-section type = Manufactured yes, if Cross-section type = Compound yes, if Cross-section type = General	This field is required only if Cross-section type is Manufactured or Compound. Defines name of the industrially manufactured profile in the globally common format (naming). For Cross-section type = general, name reference to valid CompositeShapeDef object is required in the cell “Profile”
Form code	Enum	1	yes, if Cross-section type = Manufactured	This field is valid only if profile type is Manufactured. It helps to define hot rolled or cold formed profiles. The shape of the cross-section is uniquely identified by a so-called Formcode. The Formcode defines the shape and in some cases also additional parameters like distance between bolt holes, unit warping coordinates etc. Complete list of supported form codes is attached in Formcodes.
Description ID of the profile	Enum	2	no	This field is valid only if the cross-section type is Manufactured. The description of the hot rolled and cold formed cross-section referring to the source of manufacturer. Complete list is attached in Description ID of the profile.
A [m2]	Double	0.075484	no	Section area
Iy [m4]	Double	0.000641	no	Moment of inertia about y-axis
Iz [m4]	Double	0.013319	no	Moment of inertia about z-axis
It [m4]	Double	0.0000591	no	Torsion moment of inertia
Iw[m6]	Double	0.00015548	no	Warping constant
Wply [m3]	Double	0.029497	no	Plastic modulus about the y-axis
Wplz [m3]	Double	0.029497	no	Plastic modulus about the z-axis
Id	String	6bbd256e-0225-4ee5-91e5-c7ef791a33cb	no	Unique attribute designation

Notes

The general cross-section shape definition and is represented as a separate sheet CompositeShapeDef in Excel. It is required when the cross-section type is “General”.
