Property Name (mandatory) |
Property Description and Allowed Values |
Property Value |
Reference |
Reference ID for this specified type in this project (e.g. type A-1 ), provided, if there is no classification reference to a recognized classification system used. |
|
n/a |
AcousticRating |
Acoustic rating for this object.
It is provided according to the national building code. It indicates the sound transmission resistance of this object by an index ratio (instead of providing full sound absorbtion values). |
|
n/a |
FireRating |
|
n/a |
Combustible |
Indication whether the object is made from combustible material (TRUE) or not (FALSE). |
|
false |
SurfaceSpreadOfFlame |
Indication on how the flames spread around the surface, It is given according to the national building code that governs the fire behaviour for materials. |
|
n/a |
ThermalTransmittance |
Thermal transmittance coefficient (U-Value) of a material. Here the total thermal transmittance coefficient through the slab (including all materials). |
|
0. |
IsExternal |
Indication whether the element is designed for use in the exterior (TRUE) or not (FALSE). If (TRUE) it is an external element and faces the outside of the building. |
|
false |
LoadBearing |
Indicates whether the object is intended to carry loads (TRUE) or not (FALSE). |
|
false |
Compartmentation |
Indication whether the object is designed to serve as a fire compartmentation (TRUE) or not (FALSE). |
|
false |
PitchAngle |
Angle of the slab to the horizontal when used as a component for the roof (specified as 0 degrees or not asserted for cases where the slab is not used as a roof component).
The shape information is provided in addition to the shape representation and the geometric parameters used within. In cases of inconsistency between the geometric parameters and the shape properties, provided in the attached property, the geometric parameters take precedence. For geometry editing applications, like CAD: this value should be write-only. |

ToppingType |
Defines if a topping is applied and what kind. Values are “Full topping”, “Perimeter Wash”, “None |
|
n/a |
EdgeDistanceToFirstAxis |
The distance from the left (‘West’) edge of the slab (in the direction of span of the components) to the axis of the first component. |
|
0. |
DistanceBetweenComponentAxes |
The distance between the axes of the components, measured along the ‘South’ edge of the slab. |
|
0. |
AngleToFirstAxis |
The angle of rotation of the axis of the first component relative to the ‘West’ edge of the slab. |
|
0. |
AngleBetweenComponentAxes |
The angle between the axes of each pair of components. |
|
0. |
NominalThickness |
The nominal overall thickness of the slab. |
|
0. |
NominalToppingThickness |
The nominal thickness of the topping. |
