Prestressing reinforcement (PRE-Stress)
Prestressed reinforcement is defined using the following parameters. It is also important to select the bar type to get the correct geometrical properties.
fyk: Characteristic yield stress [MPa]
fuk: Ultimate tensile strength [MPa]
Esk: Ultimate tensile strength [MPa]
εud: Elongation of reinforcement at maximum load [-]
εlimit: Limit elongation [-]
γs: Partial factor for steel materials [-]
Bar type
For prestressed reinforcement of Wire and Single wire types, it is possible to set a reinforcement diameter of the following dimensions:

For predefined materials a specific set of wires are used with specific areas. that is why a user defined material and a predefined material may have different cross section areas.
