Prestressing reinforcement (PRE-Stress)
Version 9.2 by Fredrik Lagerström on 2021/03/03 08:30
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:
- 6.90 mm (Area: 29 mm2)
- 7.00 mm (Area: 30 mm2)
- 8.00 mm (Area: 38 mm2)
- 9.00 mm (Area: 50 mm2)
- 9.30 mm (Area: 52 mm2)
- 9.60 mm (Area: 55 mm2)
- 11.00 mm (Area: 70 mm2)
- 11.30 mm (Area: 75 mm2)
- 12.50 mm (Area: 93 mm2)
- 12.90 mm (Area: 100 mm2)
- 13.00 mm (Area: 102 mm2)
- 15.20 mm (Area: 139 mm2)
- 15.70 mm (Area: 150 mm2)
