Question about pretentioning (not post-tensioning)

SOFiSTiK
1

Tendon → SYST → BETA, MUE, ECC, SP, DO.
Looks like these parameters are for post-tensioning only.

  1. Should I input zero for these parameters for pretentioning?
  2. Is there any example for pretentioning structure?
  3. Is there any things I should pay attention to when defining a pretentioning structure?

Hello

For precast pre-tensioned girders please see the following example.

Here it is important to define a special prestressing system without friction and slip.
In order to consider the immediate bond, you have to select the same construction stage for ICS1 and ICS2 in the CS command.
