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.
