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:
Name of the column header
Type of data
Value example or enum definition
Human readable unique name of the material *see notes
The type of material
The subtype of the material, e.g. hot rolled, cold formed, stainless steel, prestressed concrete, fiber-reinforced concrete, UHPC etc.
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]
Self-weight of the material
E modulus [MPa]
Young's modulus of elasticity
G modulus [MPa]
Thermal expansion [1/K]
The coefficient of thermal expansion of the material
1|1.1; 2|4.8; 9|1100
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.
