How is creep modeled?
Answer: There are several ways to model creep deformation. Depending on design intention, two options are as follows:
...
Answer: Creep coefficients are equivalent to the ACI 9.5.2.5 time-dependent factors for sustained loading, in which a creep coefficient of 2.0 corresponds to 5 years or more, 1.4 corresponds to 12 months, etc.
The method implemented within Software within CSI Software is based on Ghali, A., Favre, R., Elbadry, M. (2002). Concrete Structures: Stresses and Deformations: Analysis and Design for Serviceability (3rd ed.). London, England: Spon Press., which is similar to that of ACI 435R Appendix B, in which creep factors are analogous to those of ACI 318.
- Verification example 16, available through Help > Documentation, is also available for additional details on creep and its formulation.
