Select Materials in the Job Preferences dialog and click the Modification button. Select the Steel tab to access the following parameters.
Define the following:
Name
The name of the defined steel.
Note: The material name must be assigned before the Add button is pressed.
Description
Field for description of the defined steel.
Note: From version RSA2026 Eurocode material database has been modified and now it is possible to select materials dedicated to an appropriate version of EC3 design code. Description of a selected steel indicates dedicated design code version.
Elasticity
- Young Modulus - the value of Young's modulus for the defined steel.
- Poisson ratio - the value of Poisson's ratio for the defined steel.
- Shear modulus - the shear modulus for the defined steel. This influences shear forces on structure deformation.
Resistance
- Characteristic / design resistance - the value of the characteristic or design resistance of the defined steel.
- Reduction coefficient for shear - the reduction factor for shear analysis. The factor value is greater than 1.0.
Note: The shear reduction factor is used during structure code calculations for steel codes CM66, DIN and MV103. The shear reduction factor also refers to aluminum code AL76.
- Limit strength for tension - the limit strength for tension for the defined steel.
Others
- Density (unit weight) - the density (unit weight) of the defined steel.
- Thermal Expansion Coefficient - the thermal expansion coefficient for the defined steel.
- Damping Ratio - the damping ratio of the defined steel.
