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.
In our Knowledge Base, you will find valuable technical articles on the topic of "structural analysis" to support you in your daily work. In addition, you will receive tips & tricks for the correct and effective application of our structural analysis programs.
- How can I modify stiffnesses of particular members using a factor in RFEM 6 and RSTAB 9?
- Right after starting the program, I get the error message "Assertion failed!" What can I do to solve this problem?
- 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 the RFEM 6 Concrete Design add-on automatically design member and surface reinforcement?
- 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?
- 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.
RFEM 6 structural analysis software is the basis of a modular software system. The main RFEM 6 program is used to define structures, materials, and loads of planar and spatial structural systems consisting of plates, walls, shells, and members. The program also allows you to create combined structures as well as to model solid and contact elements.
The RSTAB 9 structural frame analysis and design program contains a similar range of functions as the FEA RFEM software, paying special attention to frameworks. It is, therefore, very easy to use and has for many years been the best choice for structural analysis of beam structures consisting of steel, concrete, timber, aluminum, and other materials.
