- •
Thermal creep and relaxation tests of prestressing steel are used for validation.
- •
Harmathy’s creep model is enhanced by inclusion of tertiary creep.
- •
Parameters of the enhanced creep model are determined.
- •
Thermal creep and relaxation can be accurately predicted.
- •
Proper choice of thermal creep parameters is important to accurate prediction.
