Is the statically indeterminate part of internal forces considered due to prestressing force in RF-TENDON?


Yes, this value is taken into account. The internal forces can also be output accordingly with respect to the prestress (see Figure 1).

Primary Forces: statically determined part of internal forces due to prestress

Secondary Forces: statically indeterminate part of internal forces due to prestress

To display the individual parts, you have to create a new result class (RC) where only the reference of the prestress load is selected.
