Should "Approximate Tendon Losses" should be checked when construction stage analysis is included?
There are two ways to consider long-term losses of prestress in midas Civil.
1) Apply Time Dependent Material (Creep & Shrinkage) during the construction stage analysis.
2) Apply 'Approximate Tendon Losses' function.
Thus, it is not necessary to use 'Approximate Tendon Losses' function if you define Time Dependent Material (Creep & Shrinkage) during the construction stage analysis.
