Product Features Articles
RF-/STEEL SIA | Features
- Design of members and set of members for compression, bending, shear, and combined actions
- Stability analysis of buckling and lateral-torsional buckling
- Automatic determination of critical buckling loads and critical buckling moments for general load applications and support conditions by means of a special FEA program (eigenvalue analysis) integrated in the module
- Optional application of discrete lateral supports to beams
- Automatic cross-section classification (Class 1 to 4)
- Deformation analysis (serviceability)
- Cross-section optimization
- Wide range of cross-sections available, for example rolled I‑, C‑ and T‑sections, angles, rectangular and circular hollow sections, round bars, symmetrical, asymmetrical and parameterized I‑ and T‑sections as well as angles and double angles
- Optional import of buckling lengths from the RF-STABILITY/RSBUCK
- Detailed result documentation with references to the design equations used and described in the standard
- Various filter and sorting options of results including result lists by member, cross-section, x-location or by load cases or load and result combination
- Result window of member slenderness and governing internal forces
- Parts list with weight and solid specifications
Frequently Asked Questions (FAQ)
- Is it also possible to reduce the shear force on a support or perform design with the shear force at a distance d to the support in RF‑CONCRETE Surfaces?
- When performing "manual definition of the reinforcement areas" in RF‑CONCRETE Surfaces, do I have to completely reinforce the entire structural component manually? Or does RF‑CONCRETE Surfaces apply the required reinforcement in the areas where I have not performed the manual definition?
- How can I consider loads from the self-weight as "favorable" and "unfavorable" for the combinations?
- When I create a user-defined result value, the RFEM solver window opens briefly and the calculation is apparently performed again. Why? I have already performed the calculation before.
- For design with CONCRETE NL, is the creep applied to the entire cross-section, or to the concrete compression zone only?
- For a specific combination rule, I would like to consider a load case with a combination coefficient that deviates from the standard. How can I proceed?
- Is the compression reinforcement calculated for the ultimate limit state design in RF‑CONCRETE Surfaces? Or is it only possible in RF‑CONCRETE Members?
- I design a combined structure made of timber materials with different creeping parameters. How can I perform the serviceability limit state design according to EN 1995‑1‑1?
- In the RF-/DYNAM Pro - Equivalent Loads module, it is possible to take accidental torsional effects into account.. Which calculation approach is behind the calculation? Which values have to be entered for the eccentricities eX and eY?
- Which programs and add-on modules by Dlubal Software are available for reinforced concrete structures?
