Service
- 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
