All elements and loadings in the FE model are assigned an analysis interval when it enters the system. CIP RC/PT Girder is based on three analysis/design cases:Initial, Final and Final w/o Sway. A fourth interval is used to account for time effects and is added between the Initial and Final cases. The user cannot see this case in any of the drop-down fields in the user interface

All elements enter in the Initial case, as well as PT and rebar. Loads enter the system depending on when they are added. The structure boundary conditions are changed in the Final w/o Sway case to fix all longitudinal displacements.
