The model is constructed by means of parameters for geometry and loads and regenerates when the parameters are changed.
- 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
- After the design with RF-/TIMBER Pro, I had a cross-section optimized. Why is the utilization of the optimized cross -section now exceeded?
- Why are the stresses of the 90 ° orientation not displayed in RF-LAMINATE for a layer with the orthotropic direction 90 ° for σb, 90?
- In RF-/STEEL EC3, is the "Elastic design (also for cross-section class 1 and 2)" option under "Details → Ultimate Limit State" considered for the stability analysis when activated?
- 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?
- Why do I get such a small amount of reinforcement for the upstand beam? The amount of reinforcement for the downstand beams is significantly larger.
- How are the creep and shrinkage for columns considered in RF‑CONCRETE Members?
- 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?
- Is it possible to display more values for the stress distribution over the layers in RF‑LAMINATE?
- Which Dlubal Software programs can I use to calculate and design timber structures?
- I would like to design an aluminum or lightweight structure. Is it possible to use RFEM or RSTAB for this?
