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:

Specification in excel:

Name of the column header	Type of data	Value example or enum definition	Required value	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

Notes

"Name" is recommended to set the same as the "Quality" of the defined material.
