Display extended strains of members, surfaces and solids (e.g. important principal strains, equivalent total strains, etc.) in the Project Navigator - Results in RFEM as well as in Table 4.0.
For example, you can display governing plastic strains when performing the plastic design of connections with surface elements.
Frequently Asked Questions (FAQ)
- I design a set of members using RF‑/STEEL EC3. In accordance with the manual calculation, the design is fulfilled, but it cannot be performed successfully in the add-on module. Why?
- I compare the flexural buckling design according to the equivalent member method and the internal forces according to the linear static analysis with the stress calculation according to the second-order analysis including imperfections. The differences are very large. What is the reason?
- Can I quickly optimize all cross-sections in my model by using internal forces?
- Is it possible to calculate and design "temporary structures"? What do I need for this?
- How can I create a twisted beam in RFEM?
- How can I perform the design of the tension resistance of a smooth column in a smooth bucket column base, that is, the design against pulling out the column?
- In the RF‑/STEEL EC3 add-on module, I obtain an extremely high design ratio for a member in the case of "Biaxial bending, shear and axial force." Although the axial force is relatively high, the design ratio seems to be unrealistic. What is the reason?
- For which programs is the STEEL Warping Torsion add-on module available?
- I have just noticed that the STEEL EC3 add-on module also calculates with γM0 = 1.0 when designing a tension member, although it should actually be γM2 = 1.25. How can I perform the design correctly?
- Is it possible to design intermittent welds in the CRANEWAY add-on module?
