- Normal stresses σx from axial force and bending
- Shear stresses τ from shear force and torsion
- Equivalent stresses σv with comparison to limit stress
- Stress ratios related to equivalent stresses
- Normal stress σx from unit normal force N
- Shear stress τ from unit shear forces Vy , Vz , Vu , Vv
- Normal stress σx from unit moments My , Mz Mu , Mv
- For a buckling analysis, FE‑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?
- Which Dlubal Software programs are required to calculate membrane and tensile structures?
- I would like to analyze cable and tensile structures. Is it possible to use RFEM or RSTAB for this?
- How can I design any SHAPE‑THIN cross-section in detail in RFEM or RSTAB?
- How can I display the stresses in the stress points in RF‑STEEL Members?
- What is the difference between the RF‑/STEEL and RF‑/STEEL EC3 add-on modules?
- 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?
- In spite of having defined smooth ranges, they are not considered in the design in RF‑STEEL Surfaces. What setting have I missed here?
- How can I perform a buckling analysis for a surface in RFEM?
- Why do I obtain much higher design ratios in RF‑/STEEL than for cross-section design in RF‑/STEEL EC3?
