Types of active rules
The available ACI 318-02 active rules are:
| Setting | Description |
|---|---|
| Code Minimum Design |
Rules for minimum reinforcement (shrinkage, detailing, etc.) based upon geometry rather than stress or moment level. Does not include shear reinforcement. |
| User Minimum Design | Reinforcement based on user defined reinforcement ratio. See the design strip property description in chapter 22. |
| Initial Service Design | Checks of PT floor stresses just after application of prestress (when dead load is minimal). |
| Service Design | Checks of PT floor stresses due to service loads. Rules for reinforcement bar based upon bar stress levels. |
| Sustained Service Design | Checks of PT floor compression stresses due to sustained loads. |
| Strength Design | Rules to ensure section has sufficient strength in bending and shear for factored (or ultimate) moments, and minimum shear reinforcement. |
| Ductility Design | Rules intended to produce ductile behavior. |
| Soil Bearing | This is used in mat foundation (raft) files to facilitate the enveloping of soil bearing pressure. It does not use any active rules. |
