BH.oM.Structure.SurfaceProperties.Ribbed¶
Property for 2D analytical elements, made up of a slab on top of parallel ribs running in one direction, all sharing the same material.
Class structure¶
Implemented interfaces and base types¶
The Ribbed is inheriting from the following base type(s) and implements the following interfaces:
- BH.oM.Base.BHoMObject
- BH.oM.Base.IBHoMObject
- BH.oM.Base.IObject
- BH.oM.Structure.SurfaceProperties.ISurfaceProperty
- BH.oM.Structure.IProperty
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 | The thickness of the slab sitting on top of the ribs. | Length [m] |
Material | IMaterialFragment | Homogenous structural material throughout the full thickness of the element. | - |
Direction | PanelDirection | Specifies if the ribs are running in local x or y direction. | - |
TotalDepth | double | Total depth measured from the bottom of the ribs to the top of the slab. | Length [m] |
StemWidth | double | Width of each rib. | Length [m] |
Spacing | double | Centre-centre distance between the ribs. Measured perpendicular to the rib direction. | Length [m] |
PanelType | PanelType | Defines what type of element this property will be used. Used by some analysis packages. | - |
Inherited properties¶
The following properties are inherited from the base class of the object
Name | Type | Description | Quantity |
---|---|---|---|
BHoM_Guid | Guid | - | - |
Fragments | FragmentSet | - | - |
Tags | HashSet<string> | - | - |
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 |
Description | string | Generates a default description for the SurfaceProperty as 'Ribbed Depth Spacing StemWidth - MaterialName'. | - | 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 |
MassPerArea | double | Calculates the mass per area for the property as its average thickness mutiplied by the density. | MassPerUnitArea [kg/m²] | 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. |

TotalThickness | double | Gets the total thickness of the surface property. | Length [m] | Structure_Engine |
VolumePerArea | double | Gets the volume per area of the property for the purpose of calculating solid volume. | Length [m] | Structure_Engine |
