- •
Creep and recovery constitutive model for cables net structures is investigated.
- •
Cable's elongation rigidity is considered as a time-dependent parameter.
- •
Force density method is used to establish the time-dependent nonlinear static equilibrium equations.
- •
The proposed method enables us to re-optimize the initial pretensions conveniently.
- •
The proposed method enables us to predict the service life of cable net structures.
