This technical article presents some basics for using the Torsional Warping add-on (7 DOF). It is fully integrated into the main program and allows you to consider the cross-section warping when calculating member elements. In combination with the Stability Analysis and Steel Design add-ons, it is possible to perform the lateral-torsional buckling design with internal forces according to the second-order analysis, taking into account imperfections.
- Right after starting the program, I get the error message "Assertion failed!" What can I do to solve this problem?
- How can I modify stiffnesses of particular members using a factor in RFEM 6 and RSTAB 9?
- Is it possible to import the coordinates of another point?
- Where can I activate the "Favorable permanent actions" option in RFEM 6 and RSTAB 9 in order to combine the self-weight in the ultimate limit state with 1.0?
- How can I neglect torsion in the steel and timber design?
- Can I define a different bar size in the RFEM 6 Concrete Design add-on other than the default bar sizes available in the drop-down?
- Can the RFEM 6 Concrete Design add-on automatically design member and surface reinforcement?
- How can a model be regenerated or where can I adjust the model tolerances?
- How can I deactivate the consideration of shear stiffness for a cross-section calculation?
- What is the reason for changing the colors for compression and tension in RFEM 6 and RSTAB 9 with respect to previous program versions? Since then, compression was red and tension was blue.
