In addition to the standard-compliant determination of wind loads and snow loads according to EN, CTE, ASCE, and DIN, it is also possible to convert surface loads into member loads. Furthermore, free line loads and coating loads (for example, ice) as well as surface loads on openings can be converted into member loads. In addition, the member, surface and solid loads from motion (brake or acceleration forces et cetera) can be generated automatically.

The load generators are accessible via 'Tools' → 'Generate Loads'.
The RF-/STEEL EC3 add-on module automatically transfers the buckling line to be used for the flexural buckling analysis for a cross-section from the cross-section properties. In particular for general cross -sections, but also for special cases, the assignment of the buckling line can be adjusted manually in the module input.
The number of degrees of freedom in a node is no longer a global calculation parameter in RFEM (6 degrees of freedom for each mesh node in 3D models, 7 degrees of freedom for the warping torsion analysis). Thus, each node is generally considered with a different number of degrees of freedom, which leads to a variable number of equations in the calculation.
This modification speeds up the calculation, especially for models where a significant reduction of the system could be achieved (e.g. trusses and membrane structures).
- Why do I get high differences when designing a longitudinally stiffened buckling panel compared to the German and Austrian National Annexes?
- How can I create a curved or curved section?
- Is it possible to manually specify a longitudinal reinforcement for the design in RF-PUNCH Pro?
- 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?
- Does the load generation also work for curved members?
If I do not specify any basic reinforcement in RF-CONCRETE Surfaces, I get the value X as additionally required reinforcement. If I enter this value X as the existing basic reinforcement, I correctly do not get any additional required reinforcement.
However, if I enter a lower value than the determined required total reinforcement as the basic reinforcement, the additionally required reinforcement is increased in such a way that the originally required reinforcement content is exceeded. Why?
- 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?
- I would like to calculate and design "temporary structures." What do I need for this?
- I often edit the reinforcement provided by the program. Adjusting the reinforcement by using coordinates takes much effort and time if having several beams in the model. Is there any way to speed up the reinforcement editing?
