Limit Values for Shear Stresses from Torsion in RF-/STEEL EC3
Very small torsional moments in the members to be designed often prevent certain design formats.
- I am designing a set of members using the equivalent member method in RF‑/STEEL EC3, but the calculation fails. The system is unstable, delivering the message "Non-designable - ER055) Zero value of the critical moment on the segment".What could be the reason?
- Why are the equivalent member designs grayed out in the Stability tab when activating the plastic designs using the partial internal force method (RF‑/STEEL Plasticity)?
- How can I create a drilled beam in RFEM?
- How does the activation of the precamber imperfection work?
- Are the models and presentations from Info Day 2020 freely available, and can you send them to me?
- What is the difference between the RF‑/STEEL and RF‑/STEEL EC3 add-on modules?
- I am performing a stability analysis of a beam for lateral-torsional buckling. Why is the modified reduction factor χLT,mod used in the design according to DIN EN 1993‑1‑1, 6.3.3 Method 2? Is it possible to deactivate this?
- I need to define different types of lateral intermediate restrains for a single element in RF-/STEEL EC3. Is this possible?
- I am comparing 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 could be the reason for this?
- How can I perform a stability/buckling analysis on a plate structure?
