BH.oM.Structure.SurfaceProperties.HollowCore

Property for 2D analytical elements, made up of a fixed thickness slab of homogenous material, with a series of parallel holes through it in a particular direction.

Class structure

Implemented interfaces and base types

The HollowCore is inheriting from the following base type(s) and implements the following interfaces:

Properties

Defining properties

The following properties are defined on the class

Name Type Description Quantity
Name string A unique Name is required for some structural packages to create and identify the object. -
Thickness double Defines the distance the element should be extruded along its normal. By default the element will be extruded half the thickness 'upwards' and half the thickness 'downwards' meaning the element base geoemtry will be in the centre of the extrusion. Length [m]
Material IMaterialFragment Homogenous structural material throughout the full thickness of the element. -
PanelType PanelType Defines what type of element this property will be used. Used by some analysis packages. -
Openings IHollowCoreOpeningProfiles Openings of the hollow core. -
Direction PanelDirection Specifies if the hollow cores are running in local x or y direction. -

Inherited properties

The following properties are inherited from the base class of the object

Name Type Description Quantity
BHoM_Guid Guid - -

CustomData Dictionary<string, object> - -

Derived properties

The following properties are defined as extension methods in one of the BHoM_Engines

Name Type Description Quantity Engine
Construction Construction Creates a physical Construction from a structural ISurfaceProperty. Extracts the Structural MaterialFragment and creates a physical material with the same name. - Structure_Engine
DescriptionOrName string Gets the name from a IProperty. If null or empty, a default description name is provided instead. - Structure_Engine
HasModifiers bool Checks if a SurfaceProperty has any modifiers by first checking if any modifiers has been assigned, and if any of them are set to a value different than 1. - Structure_Engine
IConstruction Construction Creates a physical Construction from a structural ISurfaceProperty. Extracts the Structural MaterialFragment and creates a physical material with the same name. - Structure_Engine
IDescription string Generates a default description for the SurfaceProperty, based on type, dimensions and material. - Structure_Engine
IDescription string Generates a default description for the IProperty, based on its properties. - Structure_Engine
IMassPerArea double Calculates the mass per area for the property. MassPerUnitArea [kg/m²] Structure_Engine
IMaterialComposition MaterialComposition Returns a SurfaceProperty's MaterialComposition. - Structure_Engine
InvalidSurfaceProperty bool - - Lusas_Engine
IsNull bool Checks if a SurfaceProperty is null and outputs relevant error message. - Structure_Engine
ITotalThickness double Gets the total thickness of the surface property. Length [m] Structure_Engine
IVolumePerArea double Gets the volume per area of the property for the purpose of calculating solid volume. Length [m] Structure_Engine
Modifiers double[] Gets any modifiers from a property as an array of doubles. The modifiers are used to scale one or more of the property constants for analysis. Constants are multiplied with the modifiers, hence a modifier value of 1 means no change.
The values returned are in the following order: FXX, FXY, FYY, MXX, MXY, MYY, VXZ, VYZ, Mass, Weight. Method returns null if no modifiers are found.		 - Structure_Engine
TotalThickness double Gets the total thickness of the surface property. Length [m] Structure_Engine
VoidZoneHeight double Gets the height of the hollow core zone of the hollow core property. Length [m] Structure_Engine
VoidZoneSolidRatio double Gets the ratio of solid material to void in the opening sone of the HollowCore, where 1 means no voids and 0 means complete void. Please note that this only relates to the thickness zone with voids, not including solid areas at top and bottom. Ratio [-] Structure_Engine
VolumePerArea double Gets the volume per area of the property for the purpose of calculating solid volume. Length [m] Structure_Engine
