B.6.2 ACI 209 Model Code Creep

In a model for transient nonlinear analysis you may specify a creep model for concrete according to the ACI 209 Model Code.

ACI 209 Model Code creep				§7.4.2.2
no parameters

B.6.2.1 Cement Class

For the ACI 209 Model Code creep model you must specify the cement class.

Class I cement
