Regular reinforcement (PRE-Stress)

Last modified by Fredrik Lagerström on 2021/03/01 12:56

Regular reinforcement is defined using a specific setup of 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 regular reinforcement of Plain, Ribbed and Profiled types, it is possible to set a reinforcement diameter of 1-99mm in 1mm increments
