Modelling of Tower with Block Manager
Lattice towers represent typical applications in steel construction. Examples for this special type of truss structures are antenna and overhead line towers, or columns for wind power stations, cable cars, and supporting frame constructions.Screenshots

Material Database with Steels According to the Australian Standard AS/NZS 4600:2005
The material database in RFEM, RSTAB and SHAPE-THIN contains steels according to the Australian standard AS/NZS 4600:2005.Frequently Asked Questions (FAQ)
- 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?
- I design a cross-section created in the SHAPE‑THIN program by using the RF‑STEEL EC3 add-on module, but the program shows the error message "ER006 Invalid type of c/t-part for cross-section of type General." What can I do?
- 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?
- Why do I get a design ratio for the stability analysis according to 6.2.9.1 in the STEEL EC3 add-on module? Why is a * added to Equation (6.36)?
- I design a frame with a taper (docked cross-section). STEEL EC3 classifies the taper in Cross-Section Class 3. Accordingly, the elastic resistances are taken into account, which is very unfavorable. According to the standard, the taper should be categorized in Class 1, and thus the plastic reserve should also be usable.
- When modeling a beam connection to a continuous column, I have the problem that the column flange fails under bending. If I add backing plates in the FRAME‑JOINT Pro add-on module, nothing changes for all design ratios. Why?
- I would expect the results from my load combination (CO) set to a linear analysis to equal the summation of the results from my load cases (LC) also set to a linear analysis. Why do the results not match?
