  • Tendons are considered as an external load (and the balance loading is assumed to be included in the load factors).
  • The reinforcement type (as defined in the design section or design strip segment) is considered (PT or RC).
  • The stress levels in the structure are determined by the moment envelope for the rule set (reinforcement may be required on both faces).
  • The design strip segment or design section property "Environment" is used to determine the class of post-tensioned members as follows:
    • Protected: Class C
    • Normal: Class T
    • Corrosive: Class U
    • Very Corrosive: Class U
  • Code Rules are applied as shown in the following table
