Define parameters for concrete based on the ACI209R-92 model.
The ACI 209R-92 model is only used for time-step analysis.
Item | Description |
---|---|
Use time parameters from ACI 209R-92, Prediction of Creep, Shrinkage, and Temperature Effects in Concrete Structures | When checked, the parameters a and Beta are taken from the ACI 209R-92 document. Otherwise a and Beta are input directly. |
Cure Method | Select a cure method. Used in determining a and Beta. |
Cement Type | Select a cement type. Used in determining a and Beta. |
a | A parameter used in ACI 209R-92 equation 2-1. |
Beta | A parameter used in ACI 209R-92 equation 2-1. |
