Internal forces are required to determine the effective cross-section and stresses.
The internal forces are managed in load cases or load combinations (see the chapter Load Cases and Combinations ).
You can define the internal forces in the dialog box or in the table. Furthermore, you can import the internal forces from RFEM or RSTAB using the Tools menu or the
button in the Internal Forces table. The import of internal forces is described in the chapter
Import of Internal Forces
.
