Reinforcement Properties
Description
Definition of the material properties for a section or beam is a three step process:
- Add the material type (concrete / reinforcing steel / etc.)
- Define a set of properties for that material type (characteristic strength etc.)
- Allocate the material properties defined in 1 & 2 to the relevant parts of the section or beam section component.
This form performs the second of these 3 stages for reinforcement. As data is entered the program checks that values are within the expected range for steel. This check will highlight any values in error by a factor of 10 more. The displays for Ultimate Limit State and Servicability Limit State are to the same scale, and are updated as the values in the fields are changed.
Relevant nationally determined parameters are displayed in this form, but these may only be edited in the Nationally Determined Parameters Form accessible through the NDP Values button.

Field Help
Yield strength fyk
Enter the yield strength of the (hot-rolled) reinforcement. A warning will be issued if the value entered is outside the range 400 to 600MPa defined by EN 1992-1-1: Clause 3.2.2-(3), but the value will not be rejected.
Modulus of Elasticity, Es
Enter the modulus of elasticity of the reinforcement. The default value is 200kN/mm2 as defined in EN 1992-1-1: 3.2.7-(4).
Nationally Determined Parameters
The items under this heading cannot be edited in this form as they are Nationally Determined Parameters, and are present for information only. The values can however be edited on the NDP values form which can be accessed directly from the button on the right of this form.
Density
Enter the density of the reinforcement.
The default is 77kN/m3 as defined by EN 1992-1-1: Clause 3.2.7-(3).
Property name
The program will supply a reference name which provides an identifier to the material property set which is usually unique. This value may be edited to give a more readily recognisable name if required. For the Inclined Relation 'INC' is appended to the name.
