Loss due to deformation of stressing bed |
It indicates whether the loss caused by the shortening of stressing bed due to stressing of all prestressing units will be calculated. The stressing bed is an auxiliary structure between abutments where the formwork is placed. It might be of a limited stiffness relating to high forces applied during stressing. |
