Super-T Design to AS5100.5: 2017
1. Debonding length
If you don't use the wizard function, the tendon profile has to be excluding debonding area. For instance, if the debonding length is 1m for the tendon below at the begining, x coordinate has to be 1m.
You might need to utilize MCT command Shell for multiple tendon profile. All the tendon profile can be shown as text format if you search '*TDN-PROFILE' and click on 'Insert Data'. After editting the data (May be using Excel spread sheet), click 'Run' then modified profile will be applied to the model.
2. Construction Stage Analysis
Construction Stage Analysis function generate and calculate tendon primary and secondary effect seperately. And the design function applies effective prestressing forces including tendon losses. It is more accurate results especially with Time Dependent Material. However, as you mentioned, if you don't want to simulate all the sequences, if can include all of element, boundary condition and loading to single construction stage and implement PSC design. We may consider the design function without construction stages in the future.
Not all the boundary conditions and loadings has been assigned to the construction stage in your model file.
You may assign the group using the table as shown below.
Reinforcement only can be seen in Section manager as shown below.
It cannot be shown in model view.
