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?
- How are the signs to be interpreted for the release results of the line release and line hinges?
- 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?
- Why is the deflection of the reinforced concrete floor sometimes greater when selecting a larger basic reinforcement?
- 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?
