Why do I get major differences for the design of a longitudinally stiffened buckling panel in comparison with the German and Austrian National Annexes?
For a buckling analysis, PLATE‑BUCKLING determines the governing shear stress of τ = 7.45 kN/cm², while RF‑/STEEL gives the result of the maximum shear stress of τ = 8.20 kN/cm². Where does this difference come from?
The characters "<" and ">" are no longer displayed on my PC. Instead, I get wrong symbols (circles) for design ratios in the add-on module or in the printout report. Could you tell me why?
In PLATE‑BUCKLING, the reduction factor due to column buckling χc is calculated using the modified slenderness of the sheet metal ${\overline{\mathrm\lambda}}_{\mathrm p}$. Why is it not calculated using the slenderness of the equivalent compression member ${\overline{\mathrm\lambda}}_{\mathrm c}$ ?
I am using the PLATE‑BUCKLING add-on module and need more detailed information on how the critical buckling stress for the column buckling behavior is calculated. The stiffeners end before the edges. Is the eigenvalue of the stiffener calculated as a member with the effective slab width?
Dlubal Software programs should be installed on a new computer. The installation is aborted because the dongle driver cannot be installed properly. What should I do?
I have installed RFEM without problems. However, when opening the program, it does not start as a full version. A dialog box appears where the authorization file can be imported or the test license can be started. The dongle lights up and should work. What can I do?
When performing design with PLATE‑BUCKLING, all design checks are fulfilled. Nevertheless, the critical load factor is smaller than 1. Is the design fulfilled or not?
