Criteria > Construction Stage Analysis > Concrete Material Models
This command provides a means to define concrete material models. This information is used to calculate time-dependent material effects for concrete members during construction stage analysis. This section can be skipped if no time-dependent material effects are considered in stage-construction analysis.
For each concrete model type, a set of default parameters is provided (named with Label DEFAULT). Engineer can create as many concrete models with different parameters accompanied with a unique label.
Three different concrete models are implemented: ACI 209R-98, CEB MC90-99 and Model B3. Further information about these models can be found in the following reference:
