and can be easily calculated from a given strain. In this way, the iteration is bypassed with
acceptable deviation from the original curves. To calculate
A
and
R
in Equations (9.13) and
(9.14), default values of the coefficients are set as 1.9 and 10, respectively. Users can also
define the values for the coefficients.
9.2.2.2 TendonL01
The tendon module TendonL01 needed in the CSMM for prestressed concrete incorporates
both the stress-strain relationships of embedded tendons in tension, as predicted by SMM
for prestressed concrete (Figure 9.6) along with the unloading/reloading pattern of uniaxial
