IfcStructuralSteelProfileProperties

Definition from IAI: This is a collection of structural properties applicable to all linear structural members having a profile definition. These structural members are made of steel (or other metalic and isotropic material).

> HISTORY: New entity in Release IFC2x Edition 2.

Attribute definitions:

ShearAreaZ | : | Area of the profile for calculating the shear stress for a shear force parallel to the profile’s Z-axis. Usually measured in [mm2].
ShearAreaY | : | Area of the profile for calculating the shear stress for a shear force parallel to the profile’s Y-axis. Usually measured in [mm2].
PlasticShapeFactorY | : | Ratio of plastic versus elastic bending moment capacity (about y-axis) of the profile.
PlasticShapeFactorZ | : | Ratio of plastic versus elastic bending moment capacity (about z-axis) of the profile.
