StructuralMaterial¶
Material
Material is the basic entity affecting the behaviour of the structure. It is subsequently applied to a chosen profile (StructuralCrossSection). The user can use a pre-defined material or change the properties to get a custom one. The predefined materials correspond to materials defined in particular technical codes.The specification in excel:

Data type |
Example / enum definition |
Required |
Description |
---|---|---|---|---|
Name |
String |
S235 |
yes |
Human readable unique name of the material *see notes |
Type |
Enum |

The subtype of the material, e.g. hot rolled, cold formed, stainless steel, prestressed concrete, fiber-reinforced concrete, UHPC etc. |
Quality |
String |
S235 |
yes |
The quality grade of the material. Use a commonly known naming of grades of specific structural material. Example: Steel - S235, S275, S355… Concrete - C16/20, C25/30, C30/35… Timber - C18, C22, D18… |

Notes¶
“Name” is recommended to set the same as the “Quality” of the defined material.
