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:
| Column header | Data type | Example / enum definition | Required | Description |
|---|---|---|---|---|
| Name | String | S235 | yes | Human readable unique name of the material *see notes |
| Type | Enum | Concrete Steel Timber Aluminium Masonry Other |
yes | The type of material |
| Subtype | String | Hot rolled | no | 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... |
| Unit mass [kg/m3] | Double | 7850 | no | Self-weight of the material |
| E modulus [MPa] | Double | 210000 | no | Young's modulus of elasticity |
| G modulus [MPa] | Double | 12500 | no | Shear modulus |
| Poisson Coefficient | Double | 0.2 | no | Poisson coefficient |
| Thermal expansion [1/K] | Double | 0.000012 | no | The coefficient of thermal expansion of the material |
| Design properties | String | 1|1.1; 2|4.8; 9|1100 | no | Custom design characteristics of the material. The format of the data has to follow this convention: "label of the design property" "|" "value of the design property" The list of available properties with indexes can be found in Annex. |
| Id | String | 6bbd256e-0225-4ee5-91e5-c7ef791a33cb | no | Unique attribute designation |
"Name" is recommended to set the same as the "Quality" of the defined material.
