Creep and Shrinkage
The program determines concrete creep and shrinkage based on a time-dependent stress-strain law developed by Trost.
The prestressing steel single layers are included in the calculation of the creep and shrinkage load case while the entire rigidity matrix is being processed. This results in composite elements whose strain state is taken to determine the corresponding share of internal forces of the composite components. This approach is implemented for all element types. Creep redistribution can therefore also be determined for area and solid models. The necessary creep and shrinkage coefficients can optionally be calculated.
