redistributions are possible, both to the inner shaft reinforcement and also to the sides of
the most highly stressed segment of the shaft.
3.5.2 Material resistance of reinforcement
The bilinear diagram according to DIN 1045-1 [33], valid for tension and compression,
is assumed for the reinforcing steel (Figure 3.11). Tension stiffening has no effect
because tensile stresses in the concrete are not considered during the design.
The prestressing steel stress-strain curve for the detailed design also has a bilinear form
(see Figure 3.4).
